OK, that's pretty neat, but I realize now that my example was 
unintentionally misleading.  The problem is not quite as regular as I made 
it out to be.

What if I want to execute different code depending on which expression I 
matched?  Something along the lines of (pseudocode):

if (m = e1.match(line)):
   text1 = m.group(1)
   do_complicated_processing (text1)
elif (m = e2.match(line)):
   text1 = m.group(1)
   text2 = m.group(2)
   print text1, text2
elif (m = e3.match(line)):
   return
