Hash::Util::FieldHash::Compat - Use Hash::Util::FieldHash or ties, depending on availability.
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)
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.
This module is maintained using Darcs. You can get the latest version from http://nothingmuch.woobling.org/code, and use
