- * Permission is hereby granted, to either redistribute and/or
- * modify this file, provided that the conditions mentioned in the

- * @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.
