Matt,

A wothy project indeed. A couple of suggestions:

1) Don't allow a global class to inherit from a local class. The purpose of
local classes is to provide support for the global class(es) in the
file--the user of the file should only see the global classes. Should
simplify the scope rules.

2) Method overloading is a concrete b*tch for multi-parameter methods. I
tried this for Diamond and gave up. Diamond uses overloading based only on
the number of parameters. If further overloading is required, the Diamond
programmer must provide it in the method. If you want to have parametype
type overloading, I would suggest this method resolution order: considering
all methods of the class, both defined in the class and inherited search all
methods with the proper number of parameters in the order the methods were
defined and the first mathching signature is the method called. In the case
of an overridden superclass method, the search order is based on the
original method, but the method called is the overriding method. This will
assure consistent MRO's among a class and it's subclasses.
