    Nice nice article. Despite having used Perl for a number of years and become quite proficient in most parts of the language, I never really "got" the use of map and grep. Zlatanov's two central tips, "read from right to left" and "it's like foreach without an explicit looping condition" finally brought the principles home to me. I can finally read and understand The Schwartzian Transform!
