What is 'MooseX::' ?

• Namespace for Moose Extensions

• not Perl extensions written in Moose
• Cue flamewar

• General characteristics (any of, not exhaustive):

• only really useful for building Moose classes (no-end-functionality rule)
• not just Moose classes or roles
• unless those roles are also MooseX:: (association rule)
• likely to be orthogonal to function of class (users' expectations rule)
• prototypes a new Moose feature (core-in-waiting rule)
• delivers only types, ie MooseX::Types::* (types-only rule)
• API generally metarole-based (metarole rule)
