Well, it turns out to be the best way to invert a string, IMO. The 
reversed() feature returns a reversed object... not a reversed string. 
In short, I have to fool with it again _after_ it has been inverted. The 
slicing takes care of the job right away and gives me what I want... no 
Computer Sciencey <reversed object at 0xb6f6152c>> to deal with :)

I'm sure the reversed feature is much more generic though for dealing 
with other types.
