What is the hangup for regular expressions? Sure, the syntax is sort of complex… but it’s really not that hard, especially for most things. Multiple regular expressions are often handier than a single, megalithic one. Also the primary penalty is loading the regex library in the first place, so if you do need one, you might as well use more even if it could be easily replaced by logic. Assuming the regex module is fast and accurate, what else could be better?
