If you are not going to have duplicated data, I would suggest using a Hash to quick lookups. AFAIK, there is not "in" comparison like you would like to do.

Hash::Util::FieldHash::Compat(3pm)			User Contributed Perl Documentation			Hash::Util::FieldHash::Compat(3pm)

NAME
Hash::Util::FieldHash::Compat - Use Hash::Util::FieldHash or ties, depending on availability. SYNOPSIS
use Hash::Util::FieldHash::Compat; # pretend you are using L<Hash::Util::FieldHash> # under older perls it'll be Tie::RefHash::Weak instead (slower, but same behavior) DESCRIPTION
Under older perls this module provides a drop in compatible api to Hash::Util::FieldHash using perltie. When Hash::Util::FieldHash is available it will use that instead. This way code requiring field hashes can benefit from fast, robust field hashes on Perl 5.10 and newer, but still run on older perls that don't ship with that module. See Hash::Util::FieldHash for all the details of the API. SEE ALSO
Hash::Util::FieldHash, Tie::RefHash, Tie::RefHash::Weak. VERSION CONTROL
This module is maintained using Darcs. You can get the latest version from <http://nothingmuch.woobling.org/code>, and use "darcs send" to commit changes. AUTHOR
