Uh! Bad advice (the "shorten your variable names", not the map example)! Sorry, just my humble opinion. As soon as the scope of the variable you use is larger than 5 lines, use Identifiers::Long! ;) Then, if it's just 5 lines, you'll survive typing a long name two or three times either. When someone else will need to read your code -- and after 6 Months you yourself are someone else -- he'll be glad to have meaningful names. I banned $i for counters right after school (where the formula's my programs were based on used i, of course), and I never missed it. Even if it's an iteration I'd rather use $iteration_count. And in case of indices it's nice to expess what your're indexing. And let's be honest, typing $request especially in a coding situation takes me no longer that typing $r. Well almost... It surely takes more time to read (and lookup/translate and undestand) $r for anyone not knowing the obvious... If I don't want to repeatedly type an identifier with a fancy name I simply cut and paste. Of course, it's good to know how to do that using your keyboard... ;) There's enough abbreviation in Perl anyway ($_, $a, $b, $#array, etc.). So, while I'm with you that obfuscuated perl is cool and fun, yet for serious work it's cool to use @long_names, and lame to be $lzy. So long, PS: I know I am a style phanatic. Update: Humm... I just realized I talked back to a saint... :] (...) a lazy saint. ;)
