The issue you are addressing is finding the applicable methods.
The rules where to look when the object itself does not have the
method. But mechanisms like this are needed for anything that seriously
calls itself OO-language. And these mechanisms can be quite different if
we consider Perl6, Java, C++, CLOS, Smalltalk, PHP, Eiffel, Ada, Ruby or
Python (not that I know all of those...). And I understand that the
method dispatching mechanism of Parrot should be powerful enough to
cover at least Perl6, Ruby and Python. But does the way to achieve this
have to be exactly how Ruby actually does it? Or is it enough if the
way is well defined? These interlanguage-calls might have some extra
complexity, at least that's my experience whenever you do something like
that, due to different semantics.
I don't think that Parrot needs to exactly mimic the way Ruby handles
method dispatch but there does need to be a well defined way.
