> Brag that you called Perl from Python because it was "quicker" to experienced Python programmers. A coworker found that calling out to grep can be faster than using Python's regular expressions for large amounts of text processing. My first reaction was to cringe, but it was indeed much faster for this particular problem; I think I was the bad programmer for reflexively cringing instead of saying "nice performance hack".
