the problem is that scripters get excited after learning something new like regex and tend to fall under its spell. for every task they're given they'll immediately believe regex should be used to solve it. this leads to severe gaps in scripting logic
...or they are pampered by other scripting languages (perl comes to mind!) where regex _is_ the best (or, indeed, only) way to do the comparison.
Not that I would ever succumb to this, of course. *cough* *hack* *cough*
