 * Need to be very careful about how these macros are defined, especially

 *
 * VALUEFUNC(f) is a macro used to typecast a C function that implements
 * a Ruby method so that it can be passed as an argument to API functions
 * like rb_define_method() and rb_define_singleton_method().
 *
 * VOIDFUNC(f) is a macro used to typecast a C function that implements
 * either the "mark" or "free" stuff for a Ruby Data object, so that it
 * can be passed as an argument to API functions like Data_Wrap_Struct()
 * and Data_Make_Struct().
