		_delirium on July 5, 2010 \| parent \| context \| favorite \| on: A regular expression to check for prime numbers Yeah, I see regexes as more of a question of expression, in the pragmatic human programmer sense, rather than formal expressibility. Some things are natural and easy to write using regexes, and some are much better done some other way, but I'm not sure the Chomsky hierarchy shows where that boundary is.

I agree, however I feel that in almost every case, regexes are only natural for matching regular languages.
