Tim warned me that the mere attempt to read sources for
existing RE implementations was a sure way to destroy my
brain, so I avoided that.

SRE is a clean-room implementation, using the Python 1.5.2
docs and the regression test suite as the only reference.  I've
never written a Perl regexp in my life.
