Python 1.5.2 silently allows multiple keyword arguments in function definitions
as demonstrated by the following code snippet:

Python 1.5.2+ (#35, Aug 26 1999, 10:08:41)  [GCC 2.7.2.3] on linux2

>>> def f(a=0,a=0):
...   print a
... 
>>> f(3)
0

This was reported on the comp.lang.python by François Pinard.  I haven't seen
it fly by the bugs list so wanted to make sure it got recorded.
