I like Data::Alias. It seems to be broken in 5.12. Can it be fixed? Will it be fixed soon? Is there any nice alternative?
Any version of Data::Alias built before Version 1.08 (Released October 22nd, 2010 BST) won't work with Perl 5.12 as Data::Alias prior to 1.08 is broken in Perl 5.12. Upgrade to the latest version (1.08 or newer) and it should work!
As an interesting side note, it seems like being able to do aliases may be coming to Perl as a language feature in the future, with the cleanup of := no longer meaning an empty attribute list. Look forward to it! :)
