a slightly hairer design issue is what combinations
of pattern and string the new 're' will handle.

the first two are obvious:

    ordinary pattern, ordinary string
    unicode pattern, unicode string

but what about these?

    ordinary pattern, unicode string
    unicode pattern, ordinary string

"coercing" patterns (i.e. recompiling, on demand)
seem to be a somewhat risky business ;-)
