before this change, format_as() is unable to format a type which has `auto format_as() -> const another_type&`, and `another_type` is formattable. because `format_as_result` maps the result type as it is, and the compiler refuses to compile `static_cast<T*>(nullptr)`, where T is a reference type. but it would be handy if we could use `format_as()` to format types which, for instance, owns / inherit from a formattable type, and delegate the formatter to these variables instead without creating a copy of them. in this change: * instruct `format_as_result` to map the result type to the decayed type, so that `type` can be the decayed type of result type, and this also enables `type` to be formattable, as long as the decayed type is formattable. * corresponding test is added to format-test.cc Signed-off-by: Kefu Chai <tchaikov@gmail.com> |
