Strange writing not detected

[François Pinard]

Hi, people.  I made the following mistake (reduced, of course):

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

In fact, I had many keywords arguments distributed over two lines, and
just missed that one of them was repeated, and the results were unexpected.
May I suggest that the byte compiler should refuse repeated arguments?

This is Python 1.5.2.
