* @warning Symbols prefixed with either `RUBY3` or `ruby3` are
|

* implementation details. Don't take them as canon. They could

|
|
* @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.
