- Change syntax from `enum` to `enum class` (only strongly-typed enums)
- Support optional underlying type: `enum class Flags : char { ... }`
(defaults to `int` when omitted)
- Replace `from_int` with a constructor named after the enum type,
accessed as `Color::Color(1)` — the underlying type is no longer
hardcoded to int
- Use Boxed_Number for type-generic value storage and comparison
- to_underlying now returns the actual underlying type
Note: `Color(1)` syntax is not possible because ChaiScript's global
objects shadow functions with the same name; `Color::Color(1)` is the
C++-consistent alternative.

Merge upstream/develop (including namespace support from #552, WASM
support from #678, and grammar diagrams from #628) and adapt enum
implementation for compatibility with the :: dot-access semantics.
Enum values are now stored as attributes on a container Dynamic_Object,
aligning with how namespaces store members. The from_int() factory
method replaces direct constructor syntax since a name cannot be both
a global object (for :: access) and a callable constructor.

* Fix#552: Support nested namespaces via dotted names
Namespaces can now be nested using dotted name syntax, both from C++
(register_namespace(gen, "constants.si")) and from script
(namespace("constants.si")). Parent namespaces are auto-registered when
absent, and child namespaces are automatically nested into their parent
on import. This allows clean hierarchical organization like
constants.si.mu_B instead of flat names like constants_si.

* Address review: use :: instead of . as nested namespace separator
Switch from dotted names (e.g. "constants.si") to C++-style ::
separator (e.g. "constants::si") for nested namespace declarations,
both in the C++ API (register_namespace) and in script (namespace()).
The original implementation used . because namespace members are
accessed via dot notation at runtime (constants.si.mu_B), making the
declaration separator match the access syntax. However, :: is more
consistent with C++ namespace conventions and aligns with ChaiScript's
existing use of :: for method (def Class::method) and attribute
(attr Class::attr) declarations.
Member access in scripts remains dot-based (constants.si.mu_B) since
that is ChaiScript's member access operator.

* Address review: C++-style namespace scoping and block declarations
Add :: scope resolution operator for member access (ns::func works
like ns.func). Add block namespace declarations:
namespace x::y { def func() { ... } }
Functions and variables declared inside a namespace block are added
as members of the namespace, accessible via :: or dot notation.
Namespaces can be reopened to add more members, matching C++ behavior.

* Address review: extract shared make_proxy_function from Def_AST_Node
Namespace_Block_AST_Node was duplicating the entire proxy function
creation logic from Def_AST_Node::eval_internal. Extract a static
make_proxy_function helper so both nodes share the same code path,
eliminating fragile duplication that would drift if Def handling changes.

* Address review: reject non-declaration statements inside namespace blocks
Only def, var, auto, and global declarations are now allowed inside
namespace { } blocks. Arbitrary expressions, assignments, and function
calls are rejected with an eval_error. Added compiled tests verifying
that expressions, function calls, and assignments are rejected.

* Address review: remove -j parameter from unix builds
Ninja handles parallelism intelligently on its own; the explicit -j flag

build retains -j.

Remove Enum_Access AST node type — reuse Id_AST_Node for enum value
lookups by combining "EnumName::ValueName" at parse time. Replace
std::set with std::vector for valid value tracking (enums are small).

Adds the ability to define enums inside ChaiScript with syntax:
enum Color { Red, Green, Blue }
enum Priority { Low = 10, Medium = 20, High = 30 }
Enum values are strongly typed Dynamic_Objects accessed via :: syntax
(e.g. Color::Red). A validating constructor from int is registered that
rejects values outside the defined range. Functions declared with an enum
parameter type (e.g. def fun(Color val)) correctly reject plain integers,
enforcing type safety at the dispatch level.

The Return() parser function called Operator() to parse the return value,
which only handles arithmetic/logical operators but not assignments. Changed
it to call Equation(), which wraps Operator() and adds assignment parsing.
This is consistent with how If, For, and function argument parsing already
work. Enables `return foo = 5`, `return x += 1`, etc.

The saw_eol variable in Class_Statements() was initialized to true and
only ever set back to true, making the "missing line separator" check
unreachable. The fix separates Def (block statement ending with }) from
Var_Decl (simple statement) so that Var_Decl sets saw_eol to false,
matching the pattern used in Statements() for simple expressions.

* Fix#17: Add const local variable support to ChaiScript
Adds `const var`, `const auto`, and `const` as variable declaration
syntax that creates immutable local variables. A const_override flag
on Boxed_Value enables script-level constness without changing the
C++ type system integration. The parser, optimizer, and evaluator
are extended with Const_Var_Decl and Const_Assign_Decl AST nodes
that mirror their non-const counterparts but mark the value as const
after initialization.

* Address review: remove const_override, set const flag directly on Type_Info
Replace the m_const_override bool on Boxed_Value::Data with a
Type_Info::make_const() method that sets the const bit in m_flags
directly. This ensures constness is visible everywhere consistently,
including places that check get_type_info().is_const() directly.

* Fix#201: Add class inheritance support with Derived : Base syntax
Classes can now inherit methods and attributes from a base class using
C++-style syntax: `class Derived : Base { ... }`. Base class methods and
attributes are automatically available on derived objects. Derived classes
can override base methods by defining a method with the same name.
Inheritance relationships are tracked to support proper type matching
in the dispatch system.

* Address review: use implicit derived-to-base matching instead of copying base class functions
Instead of copying all base class methods/attributes into derived classes,
make the type matching system recognize inheritance relationships. Base class
methods now naturally match derived objects through dynamic_object_typename_match,
and dispatch ordering ensures derived overrides are preferred over base methods.
This is simpler (net -25 lines) and avoids duplicating function registrations.

Add C++11-style raw string literals (R"delimiter(content)delimiter") to
ChaiScript. Raw strings do not process escape sequences or perform string
interpolation, solving the issue where base85 encoded data containing ${
sequences would trigger unwanted instring_eval. The implementation adds
Raw_String_() and Raw_String() parser functions and hooks them into the
expression parser.

I initially tried to use the existing .clang-format file,
but it does not match the code style (at least with clang-format 11)
and the formatting is not consistent across files.
Therefore, I decided to rewrite the .clang-format with some personal
preferences.
Used command
find . -iname "*.hpp" -o -iname "*.cpp" | xargs clang-format -i -style=file
