#Trying to implement rb_call_super() for more RMagick fun.

VALUE rb_call_super(int nargs, VALUE *args) {
  CTX;
  VALUE obj;

  obj = NEW_HANDLE(ctx, ctx->fc->self);
  return rb_funcall2(obj, rb_intern("super"), nargs, args);
}

#This fails.  super() isn't a "real" method, so rubinius complains
#that it cannot find the method.

VALUE rb_call_super(int nargs, VALUE *args) {
  CTX;
  VALUE obj;

  obj = NEW_HANDLE(ctx, class_get_superclass(ctx->fc->self->klass));
  return _push_and_call(obj, (ID)ctx->fc->method, nargs, args);
}

#This fails.  Replacing (ID)ctx->fc->method with
#rb_intern("real method to call") also fails, as obj appears
#to be pointing to the metaclass instead of the class itself.
#Roughly, obj.metaclass.superclass.superclass.  But
#(ID)ctx->fc->method appears to be wrong anyway, it's not
#pointing to what I expected it to point to.  It's an OBJECT
#rather than an ID, and casting it doesn't appear to be the
#right thing.

#I suppose I could go through a string based eval but clearly
#at this point in the code, we know our current object and
#should be able to figure out the method lookup table of the
#parent object and make the appropriate call.  But I can't
#get it.  Help?
