Filter::CommaEquals - Adds support for ,= to any package or script
use Filter::CommaEquals; my @array = (42, 1138, 96); @array ,= 433; # exactly the same as writing: push(@array, 433); print join(', ', @array), "\n"; # prints: 42, 1138, 96, 433
Adds support for ,= to any package or script. Perl has +=, -=, /=, *=, .=, and so forth to operate on scalars, but it doesn't have ,= to operate on arrays. This module effectively lets you rewrite push statements with ,= instead.
push @array, $element; push(@array, $element_1, $element_2, $element_3); push @array, [ 42, 1138, 96, 433 ];
...can now be rewritten as...
use Filter::CommaEquals; @array ,= $element; @array ,= $element_1, $element_2, $element_3; @array ,= [ 42, 1138, 96, 433 ];
Cool, huh? Admit it. You want to write ,= instead of push, don't you. You can save typing 3 whole characters!
Filter::CommaEquals is scoped to the package or script that it's used in, but nothing more, and it requires Perl version 5.7.1 or higher.
A coworker complained about ,= not being in core Perl. After some thought, I realized writing ,= is faster (by 3 key presses) than push. Also, I'm lazy.
