The more I work with parsing, parser combinators and writing grammars for little languages, the less often I find myself using or wanting to use any regex at all. When I do, I always feel like there should be a better way, perhaps a type safe way of accessing the info I need and so on. It feels "Ugh, there should be a better way to do this." Especially in JavaScript, regexes blow in comparison to languages with named matching groups and all that. In JS regex really feels horrible, even more cryptic than in other languages.

I think regexes are often used as a quick and dirty solution to problems, which should be solved differently. But once the regex "works" and is in place, others begin to rely on that output. Over time cruft begins to accumulate and the regex is forgotten or at least never replaced with anything more appropriate.
