NAME

Tie::Diamond - Iterate the diamond operator via a Perl array

VERSION

version 0.02

SYNOPSIS

use Tie::Diamond;
tie my(@ary), "Tie::Diamond" or die;
while (my ($idx, $item) = each @ary) {
    ...
}

DESCRIPTION

This module lets you iterate the diamond operator via a Perl array. Currently the only useful thing you can do with the array is just iterate it using each(), as shown in Synopsis.

The array backend does not slurp all lines into memory (or store past lines at all, actually), so it's safe to iterate over gigantic input.

FAQ

Why?

So you can treat the diamond operator as an array. One of my modules, Data::Unixish, uses this. A function can be passed a real array (to iterate over a Perl array), or a tied array (to iterate lines from STDIN or files mentioned in arguments); they don't have to change their iteration syntax.

Can I do this?

@other = @ary; # or print @ary

Currently no. But since you are slurping all lines anyway, you might as well just do:

@other = <>; # or print <>
