1) use the strictures
2) if you use perl -l flag in the shebang you can avoid newlines at the end of your prints.
#!perl -l use strict; use warnings; my @array1 = qw(1 2 3 4 5); my @array2 = qw(a b c d e); my @array3 = qw(6 7 8 9 0); my @array4 = qw(f g h i j); while (<DATA>) { foreach (eval("$_")) { print "$_"; } print ''; } __DATA__ @array1; @array2; @array3; @array4;
UPDATE: I semi-agree with dragonchild. Personally, I just recently have been learning about the command line flags, and I have a lot of scripts where the "\n" everywhere does annoy me a bit, and I like not having to do it anymnore. But OTOH it is a bit obfu.
UPDATE2: Dragonchild opined to me that "command line switches are for use in the command line" which on reflection seems reasonable enough. So if you agree with this point of view, delete the shebang line (#!) and just call the script using "perl -l". I think I may adopt this approach myself.
Update3: (Red in the face) All right, all right! Save the -l for one-liners. Never mind.
