Although, of course, that should probably be written:
<ident> & [ <french>+ | <swahili>+ ]
or really, just
<ident> & <<french>|<swahili>>+
That last is likely to be the fastest, since a decent implementation
of character properties should cache swatches of the bitmap like Perl 5
does, or at least memoize something somewhere to keep from having
to recalculate what's french and what's swahili...
