IMHO even if regexes are powerful enough using them for representing

always need to be escaped).
I don't see the problem of having just a list of strings and a regex
for C_String.
(I DO think that having a list of regexes is an overkill BTW)
right - but if we allow List<String> then technically it is possible to
end up with more than one regex, unless we add some invariant like
is_regex (constraint.first) implies constraint.count = 1
I am inclined to think it's easier to just program it as:
across constraint as c some
is_regex (c) and pcre_matcher. matches (extract_regex (c), data) or
else c.same_string (data)
end
IN Java it would be an iteration loop with an exit if a match is found.
You get the idea :)
