* @file
* @author Ruby developers <ruby-core@ruby-lang.org>
* @copyright This file is a part of the programming language Ruby.
* Permission is hereby granted, to either redistribute and/or
* modify this file, provided that the conditions mentioned in the
* file COPYING are met. Consult the file for details.
* @warning Symbols prefixed with either `RUBY3` or `ruby3` 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.
* @brief Function overloads to issue warnings around #ANYARGS.
*
* For instance ::rb_define_method takes a pointer to #ANYARGS -ed functions,
* which in fact varies 18 different prototypes. We still need to preserve
* #ANYARGS for storages but why not check the consistencies if possible. With
* those complex macro overlays defined in this header file, use of a function
* pointer gets checked against the corresponding arity argument.
*
* ### Q&A ###
*
* - Q: Where did the magic number "18" came from in the description above?
*
* - A: Count the case branch of `vm_method.c:call_cfunc_invoker_func()`. Note
* also that the 18 branches has lasted for at least 25 years. See also
* commit 200e0ee2fd3c1c006c528874a88f684447215524.
*
* - Q: What is this `__weakref__` thing?
*
* - A: That is a kind of function overloading mechanism that GCC provides. In
* this case for instance `rb_define_method_00` is an alias of
* ::rb_define_method, with a strong type.
*
* - Q: What is this `__transparent_union__` thing?
*
* A: That is another kind of function overloading mechanism that GCC
* provides. In this case the attributed function pointer is either
* `VALUE(*)(int,VALUE*,VALUE)` or `VALUE(*)(int,const VALUE*,VALUE)`.
*
* This is better than `void*` or #ANYARGS because we can reject all other
* possibilities than the two.
*
* - Q: What does this #rb_define_method macro mean?
*
* - A: It selects appropriate alias of the ::rb_define_method function,
* depending on the last (arity) argument.
*
* - Q: Why the special case for ::rb_f_notimplement ?
*
* - A: Function pointer to ::rb_f_notimplement is special cased in
* `vm_method.c:rb_add_method_cfunc()`. That should be handled by the
* `__builtin_choose_expr` chain inside of #rb_define_method macro
* expansion. In order to do so, comparison like
* `(func == rb_f_notimplement)` is inappropriate for
* `__builtin_choose_expr`'s expression (which must be a compile-time
* integer constant but the address of ::rb_f_notimplement is not fixed
* until the linker). Instead we are using
* `__builtin_types_compatible_p`, and in doing so we need to distinguish
* ::rb_f_notimplement from others, by type.
