Is there any discussion about which versions are currently legal python 
in Python-2.x x<4? I deal with lot's of cross version maintainance 
issues and the very worst are where the syntax makes it illegal even to 
compile the files. I believe that B is legal and has implementations for 
earlier pythons available, but are others?
