Subject: Re: How to call overridden methods (finally!)

<ruby-talk:38180>

BTW, is it a bug in UnboundMethod#bind that the following doesn't work?

  class Base; def foo; puts "Base#foo"; end; end;
  class Derived < Base; end
  d = Derived.new
  Base.instance_method(:foo).bind(d).call()

If I change line 6709 of eval.c from:

  if (!((TYPE(data->oklass) == T_MODULE) ?
        rb_obj_is_kind_of(recv, data->oklass) :
        rb_obj_is_instance_of(recv, data->oklass))) {

to:

  if(!rb_obj_is_kind_of(recv, data->oklass)) {

then the above works, and doesn't appear to have any odd behavior.

?!?  Why is it this way??  This seems intentionally complicated and
counter-intuitive.

This is the only thing I miss from C++:  being able to specify "where a
method comes from" (using the scope operator in C++, but I don't care *how*
to do it as long as I *can* do it).
