Warning
  Symbols prefixed with either `RBIMPL` or `rbimpl` are implementation details. Don't take them as canon. They could rapidly appear then vanish. The name (path) of this header file is also an implementation detail. Do not expect it to persist at the place it is now. Developers are free to move it anywhere anytime at will.

Note
  To ruby-core: remember that this header can be possibly recursively included from extension libraries written in C++. Do not expect for instance `__VA_ARGS__` is always available. We assume C99 for ruby itself but we don't assume languages of extension libraries. They could be written in C++98.
