LOL!

What old perl version? Maybe you can use one of the Any::Mose like Mo

Ok, here goes, use autodia to generate an UML file of your Moose classes

Then use autodia.pl -t oldoo.tt ... to generate perl code from said UML file

Generating from moose introspection might be faster /more accurate than going the autodia route

Both options make me laugh :) upgrade upgrade upgrade upgrade upgrade :)
