* @warning Symbols prefixed with either `RBIMPL` or `rbimpl` are

|
* @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.
