The problem is that I *want* the functionality of the existing 
window_date() because that's part of what's being tested. 
Peter's suggestion of injection to the module namespace via 
functools.partial() to specify the missing parameter was the tip 
I needed to be able to write tests that exercised things properly 
without overly invasive changes to the code.  But thanks for your 
idea.
