Sorry, I should have been more clear when I said "I'm not sure how this 
works" -- I wasn't taking issue with the fact that Python lets just 
about everything be an object, simply curious about how the re.sub() 
function determined whether it should act upon a string or use a 
function.  Your explanation makes it completely clear -- there's an 
internal type check that decides which should be done based on what the 
argument is.

Thanks!
