 From the description in PDD15 I'm not sure how to hand languages

Could this be handled during compilation?
The compiler could produce the classes Foo and Foo' and use something 
like
Ruby-Class from a library.  Then Foo could contain a hidden reference to
Foo', using a convention that the compiler can handle.  I would expect 
that
the dependency on Ruby-libraries still exist, when running compiled Ruby
anywhere where Perl6 has been installed.

you're right this is something that the compiler could handle.

The problem is what happens when some Python code tries to call a class
method on a Ruby object? if Python doesn't know about the hidden
reference within Foo it won't be able to find Foo' in order to call the
method.
I think that if different languages are going to interoperate then this
either needs to be handled within Parrot, or if it is handled by the
compiler than there needs to standard approach.
