Was this just for purity, or did it fix a bug?  The regexps there were close
to being heroically careful, and even so it was somtimes uncomfortably slow
using the class browser in IDLE (based on pyclbr), and even on a fast
machine.  A factor of 3 or 4 might make that unbearable.

If it was for purity, note that tokenize is also based on mounds of regexp
tricks <wink>.
