> I do not agree it is reasonable to declare that regular expressions are a bad DSL simply because it is possible (however common) for people to write difficult to read, or difficult to understand regular expressions. I would not call RE a bad language - they are simply too useful for that. I would argue, though, that it's a reasonable design criticism to say - not that it's possible to write difficult to read code - but that it difficult to write easy to read code.
