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

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

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:
