Language:


I've always wanted the power of foreach(@arr) to be applied to arrays working with more than one item at a time. Perl6 does it, Perl5 with source filtering can do it, close, but no cigar. This module is an small step towards the idea, an attempt to produce a way of slicing a single array with least obtrusive syntax I can think of. Now, you can iterate over an array assigning several items per cycle, by

three items at once:

while ( my ( $x, $y, $z) = slice @arr) { ... }

or two,

while ( my ( undef, $second) = slice @arr) { ... }

or even forty-two:

while ( @a = slice @arr, 42) { ... }
