I am trying to figure out why you would want to
duplicate an RE exactly.  Is it so you can have
multiple matches stored?

In my case I want to create a new one that differs
from the old very slightly.  I can (well wanting to
do that I *really* can) see why that is handy.  But
the uses for an exact duplicate is almost achieved
by

  new_re = re


???

Cheers,
Ben
