I am done with regular expressions languages and engines. Each time I wanted to do a not so trivial usage of it, I had to re-learn the language(s) and debug it, not to mention the editing operations on top of them (sed...). This has been quite annoying. So now I code it in C or assembly fusing common-cases code templates and ready build scripts to have a comfortable dev loop. In the end, I get roughly the same results and I don't need those regular expressions languages and engines. It is a clear win in that case.
