[IronPython] RPyC and IronPython

[Ronnie Maor]

if you want to use RPyC, the fix for iter and len is to change the method
handle_getattr in Connection.py to the following:

def handle_getattr(self, oid, name):
        obj = self.box[oid]
        if name in ['__iter__','__len__']:
            def f(): return getattr(__builtins__,name[2:-2])(obj) # call
iter(obj), len(obj), etc.
            return f
        return getattr(obj, name)

I haven't received a response from tomer filiba yet (RPyC's author), but
seems to work. I'm now happily iterating over remote lists :-)
