BTW, I changed the filter docstring.  In 2.3 it will say:

>>> print filter.__doc__
filter(function or None, sequence) -> list, tuple, or string

Return those items of sequence for which function(item) is true.  If
function is None, return the items that are true.  If sequence is a tuple
or string, return the same type, else return a list.

Don't let it go to your head <wink -- and thanks>.
