// REQUIRE(std::string("12") + "34" == "1234")

/** \file
 * Why does decomposing look the way it does:
 *
 * Conceptually, decomposing is simple. We change `REQUIRE( a == b )` into
 * `Decomposer{} <= a == b`, so that `Decomposer{} <= a` is evaluated first,
 * and our custom operator is used for `a == b`, because `a` is transformed
 * into `ExprLhs<T&>` and then into `BinaryExpr<T&, U&>`.
 *
 * In practice, decomposing ends up a mess, because we have to support
 * various fun things.
 *
 * 1) Types that are only comparable with literal 0, and they do this by
 *    comparing against a magic type with pointer constructor and deleted
 *    other constructors. Example: `REQUIRE((a <=> b) == 0)` in libstdc++
 *
 * 2) Types that are only comparable with literal 0, and they do this by
 *    comparing against a magic type with consteval integer constructor.
 *    Example: `REQUIRE((a <=> b) == 0)` in current MSVC STL.
 *
 * 3) Types that have no linkage, and so we cannot form a reference to
 *    them. Example: some implementations of traits.
 *
 * 4) Starting with C++20, when the compiler sees `a == b`, it also uses
 *    `b == a` when constructing the overload set. For us this means that
 *    when the compiler handles `ExprLhs<T> == b`, it also tries to resolve
 *    the overload set for `b == ExprLhs<T>`.
 *
 * To accommodate these use cases, decomposer ended up rather complex.
 *
 * 1) These types are handled by adding SFINAE overloads to our comparison
 *    operators, checking whether `T == U` are comparable with the given
 *    operator, and if not, whether T (or U) are comparable with literal 0.
 *    If yes, the overload compares T (or U) with 0 literal inline in the
 *    definition.
 *
 *    Note that for extra correctness, we check  that the other type is
 *    either an `int` (literal 0 is captured as `int` by templates), or
 *    a `long` (some platforms use 0L for `NULL` and we want to support
 *    that for pointer comparisons).
 *
 * 2) For these types, `is_foo_comparable<T, int>` is true, but letting
 *    them fall into the overload that actually does `T == int` causes
 *    compilation error. Handling them requires that the decomposition
 *    is `constexpr`, so that P2564R3 applies and the `consteval` from
 *    their accompanying magic type is propagated through the `constexpr`
 *    call stack.
 *
 *    However this is not enough to handle these types automatically,
 *    because our default is to capture types by reference, to avoid
 *    runtime copies. While these references cannot become dangling,
 *    they outlive the constexpr context and thus the default capture
 *    path cannot be actually constexpr.
 *
 *    The solution is to capture these types by value, by explicitly
 *    specializing `Catch::capture_by_value` for them. Catch2 provides
 *    specialization for `std::foo_ordering`s, but users can specialize
 *    the trait for their own types as well.
 *
 * 3) If a type has no linkage, we also cannot capture it by reference.
 *    The solution is once again to capture them by value. We handle
 *    the common cases by using `std::is_arithmetic` and `std::is_enum`
 *    as the default for `Catch::capture_by_value`, but that is only a
 *    some-effort heuristic. These combine to capture all possible bitfield
 *    bases, and also some trait-like types. As with 2), users can
 *    specialize `capture_by_value` for their own types as needed.
 *
 * 4) To support C++20 and make the SFINAE on our decomposing operators
 *    work, the SFINAE has to happen in return type, rather than in
 *    a template type. This is due to our use of logical type traits
 *    (`conjunction`/`disjunction`/`negation`), that we use to workaround
 *    an issue in older (9-) versions of GCC. I still blame C++20 for
 *    this, because without the comparison order switching, the logical
 *    traits could still be used in template type.
 *
 * There are also other side concerns, e.g. supporting both `REQUIRE(a)`
 * and `REQUIRE(a == b)`, or making `REQUIRE_THAT(a, IsEqual(b))` slot
 * nicely into the same expression handling logic, but these are rather
 * straightforward and add only a bit of complexity (e.g. common base
 * class for decomposed expressions).

 * This is a convenience header for Catch2's Generator support. It includes
 * **all** of Catch2 headers related to generators.
 *
 * Generally the Catch2 users should use specific includes they need,
 * but this header can be used instead for ease-of-experimentation, or
 * just plain convenience, at the cost of (significantly) increased
 * compilation times.
 *
 * When a new header is added to either the `generators` folder,
 * or to the corresponding internal subfolder, it should be added here.

  /**
   * Implementation of uniform distribution on floating point numbers.
   *
   * Note that we support only `float` and `double` types, because these
   * usually mean the same thing across different platform. `long double`
   * varies wildly by platform and thus we cannot provide reproducible
   * implementation. Also note that we don't implement all parts of
   * distribution per standard: this distribution is not serializable, nor
   * can the range be arbitrarily reset.
   *
   * The implementation also uses different approach than the one taken by
   * `std::uniform_real_distribution`, where instead of generating a number
   * between [0, 1) and then multiplying the range bounds with it, we first
   * split the [a, b] range into a set of equidistributed floating point
   * numbers, and then use uniform int distribution to pick which one to
   * return.
   *
   * This has the advantage of guaranteeing uniformity (the multiplication
   * method loses uniformity due to rounding when multiplying floats), except
   * for small non-uniformity at one side of the interval, where we have
   * to deal with the fact that not every interval is splittable into
   * equidistributed floats.
   *
   * Based on "Drawing random floating-point numbers from an interval" by
   * Frederic Goualard.
