The Env::Array Perl module permits the user to treat an environment variable like a regular Perl array. Array operations are implemented to use splitting and joining based on the specified delimiter. Great for environment variables like PATH. PLEASE NOTE: This module is OBSOLETE as of Perl 5.6.0. The author submitted a patch to Perl to implement this functionality in the core Perl Env.pm module and it was accepted for the 5.6.0 release.
