Good, we have gotten around to discussing a little annoyance I've 
noticed.  I think this should behave similar to the way a Unix admin who 
is familiar with basename(1) would behave:

$ basename -s .py 
/tmp/foo.py                                                                                                                            

foo                                                                                                                                                      

$                                                                                                                                                        

$ basename /tmp/foo.py .py
foo
$ basename /tmp/foo.py /tmp/fffff.py
foo.py
$ basename -a /tmp/foo.py /tmp/fffff.py
foo.py
fffff.py
$ basename -a /tmp/foo.py /tmp/fffff.py .py
foo.py
fffff.py
.py
$ basename -s .py -a /tmp/foo.py /tmp/fffff.py .py
foo
fffff
.py
$ basename -s .py -a /tmp/foo.py /tmp/fffff.py   
foo
fffff
$

Changing the function name shouldn't be the solution, imho.  Changing 
the arguments, however, should be.

Compare the documentation yourself:
