That sounds like a very good idea.  It would be pretty easy to find  
regexes and sub in a '(?#)' comment marker (I had to look up what  
that one was!) so one would have regex syntax highlighting in  
existing code, while keeping the 'raw strings are just raw strings'  
folks happy.  For those who complain that r'(?# might just be the  
beginning of some particular, non-regex raw string, well.... too  
bad!  ;)

On a side note, it may be nice to keep a documented list of such  
'extra' features (above and beyond the straight language definition)  
in the Python bundle somewhere; for instance, the appearance of  
folding markers when a triple quote is followed by text, followed by  
a <return>, followed by another triple quote.  This regex  
highlighting feature would also qualify - otherwise, it would not be  
known to a new Python + TextMate user unless they stumbled across it  
by accident or investigated the grammar in detail...
