I hope that I'm not being too much of a nuisance, but I would like to

Niall Douglas:
If you try either of these you run into major problems - there are
too many dependency issues to do it manually. I did try shuffling
around the registrations but gave up after I had moved ten.

It seems I miss something very trivial, but why do you need to convert
default argument
to Python?

Thank you very much. By the way if it too complex, then I already have
a fix to pyplusplus, that will take into account default arguments.

Any way, I attach 3 files:
    args.py
    args.cpp
    args.patch

Please, pay attention: you will not be able to import args_ext module.
Run time error will be thrown: no to_python converted has been found
for class item
( or something similar ). It will break all existing test in that unit test.
