Okay, getting closer...

Following  page 123...

Okay... I have AWindowClass defined in script. I set a field within that
table to be another table object with a metatable I've defined in C. I 've
__index AWindowClass. AWindowClass has a .new method which takes a table and
set's that objects metatable to that of AWindowClass.

So now O=AWindowClass.new{fields and stuff} ... When
0.FunctionInProtoTypeTable() is called, it won't find it in AWindowClass and
look in the prototype's table. which it finds...Problem is, the initial
'self' state isn't be passed through...as get's done when you reference a
method with anObject:AFunction();
