|Can anyone explain to me the rationale behind moving the rb_classext_t definition into internal.h, and what I should do in 1.9.3 to access the functionality of RCLASS_SUPER? I need to access *and* set the direct superclass, even if it's a T_ICLASS, so calling rb_class_superclass() is not sufficient. Thanks!

I think Nobu considered rb_classext_t should not be disclosed to
extensions, but since some extensions already use it, it might be
better to make it public anyway.
