- * @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.
