Are moose heavy? There's mouse.

I happened across Mouse in the dependency chart of an Amazon Route53 module, so I looked it up.

• Mouse is meant to be lighter than Moose, and compile faster (for CLI and primordial CGI).
• Mouse wants to let you do s/Mouse/Moose/g and have nothing break, if it turns out Mouse isn't heavy enough.
• Mouse also exports warnings and strict for you when you use it.
• Mouse basically doesn't want to have MouseX.
• Any::Moose gives you Moose if that is already loaded, or Mouse otherwise.

So there you have it: Mouse is a lightweight Moose.  Without antlers.

Updated 2013 Feb 11: Apparently there's also Moo and it's preferred, at least for today.  Because one isn't enough in Perl.
