very nice ...

of course. Is it valid, to add a type specifier for other types (like
QString)? This would simplify automated code ...

Ok, there goes my nice PyDCOP.DCOPClient class :-) What do you do
about overloaded functions?

This is very nice stuff. This will be in rc2 ? When can we expect rc2
to be released ...

I have implemented a DCOPServer class which works along the same
lines to provide automatic marshalling for DCOPServers:

class MyDCOPServer(PyDCOP.DCOPServer):

    def __init__(self):
        PyDCOP.DCOPServer.__init__(self,
                                   name="myserver",
                                   interface="MyDCOPServer",
                                   methods=[
                                       "int foo()",
                                       "void foo(QString string)",
                                       "QCStringList bar()" ])

    def foo_(self):
        return 1234

    def foo_QString(self,s):
        pass

    def bar(self):
        return [ "This","is","a","list" ]

I support overloading by (optionally) appending the function signature
to the function name: 

    foo() (no arguments) -> foo_
    foo(QString)         -> foo_QString
    foo(int,QString)     -> foo_int_QString

    all of the above     -> foo

you either:
 - implement foo and use default args or check the types
   manually 
 - implement foo_, foo_QString and foo_int_QString

I found, using a precompiler for an interpreted language like python
is not necessary.
