I don't think that will be a problem, given that the Unicode engine
would be a separate C implementation.  A bit of 'if type(strg) ==
UnicodeType' in re.py isn't going to cost very much speed.

(Speeding up PCRE -- that's another question.  I'm often tempted to
rewrite pcre_compile to generate an easier-to-analyse parse tree,
instead of its current complicated-but-memory-parsimonious compiler,
but I'm very reluctant to introduce a fork like that.)

The world does so well without me, that I am moved to wish that I could do
equally well without the world.
