totally agree. the problem isn't "regex's are hard" - it's "math is hard". Regex's (especially real regexes that are actually regular languages) are intuitive and terse, but direct and efficient. What's hard is that even regular grammars, let alone CFG, let along non-CFG, are hard for people to grasp. The problem is HARD, not the solution!
