This proposal comes up very often. I've been around in c.l.py
for only about a year now but I saw it proposed what seems like
on a monthly basis.

When I started using python I was worried about ending up with
nasty errors based on inappropriate function calls. In practice
,it turns out, in python I almost never make the kind of errors
that this type-checking would catch...
