Filter::CommaEquals - Adds support for ,= to any package or script

SYNOPSIS ^

        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

DESCRIPTION ^

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.

For example...

        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.

MOTIVATION ^

A coworker complained about ,= not being in core Perl. After some thought, I realized writing ,= is faster (by 3 key presses) than push. I'm lazy... really lazy.

If you're not a member of PerlMonks (http://www.perlmonks.org/), you should be. My username is gryphon. Yeah, I'm a Saint; but I don't let that go to my head. I'd like to give special thanks to Larry Wall for Perl, Randal Schwartz for my initial and on-going Perl education, Sam Tregar for teaching me how to write and upload CPAN modules, and the monks of PerlMonks for putting up with my foolishness.
