Very often I wish Python would support overloads. The alternative *args,
**keyword_args approach is unreadable. It forces you to look at __doc__. In my
mind that's a sign of a poor design. One of the main advantages of modern
languages is that they formalize what you used to find in comments in older
code. E.g.:

  http://www.netlib.org/slatec/src/avint.f

Input -> const, Output -> members of struct, IERR -> exception, etc. Of course,
Python is a long way from this stone-age code. But I wish it could go even
further.

All that said, I am not going to fight this battle. :)

That would be nice. I am just worried because the Python folks tend to be
really rough, at least compared to the folks I tend to meet in my home
universe.

Cheers,
