An example where it might be useful:
m = re.match('(?:([0-9]+) ([0-9]+) ([0-9]+) ([0-9]+) (?P<rect>rect)'
               '|([0-9]+) ([0-9]+) ([0-9]+) (?P<circle>circle))',
               lineFromFile)
if m['rect']:
      drawRectangle(m[1:5])
  elif m['circle']:
      drawCircle(m[1:3], m[3])
Is that really so outlandish?
Likely; normally I would expect that drawRectangle would break on string
arguments instead of ints.  I think that the amount of usefulness
compared to problems doesn't really make this worth it.
