I fully agree.
the SRE engine already supports character classes based on
ASCII, the current locale (via ctype.h), and the Unicode char-
we should probably add more classes -- at least the full list of
POSIX [:name:] classes, and probably also unicode categories.
fwiw, I've played with adding "charset" objects to SRE, which
would allow you to plug in custom [:spam:] sets as well (e.g.
xml name chars).
