SEE ALSO

This module originates from this discussion thread: http://www.perlmonks.org/?node_id=983878

syntax

Syntax::Feature::KeysOnArray

Syntax::Feature::ValuesOnArray

Array::Each::Override (written in 2007, before Perl 5.10). Didn't find out about this module until after I uploaded Syntax::Feature::EachOnArray to CPAN. This module, although not using the syntax syntax, does everything Syntax::Feature::{Each,Keys,Values}OnArray does and more. Take a look at it.
