p5-MooseX-MungeHas

Munge your "has" (works with Moo, Moose and Mouse)

MooseX::MungeHas alters the behaviour of the attributes of your Moo, Moose or Mouse based class. It manages to support all three because it doesn't attempt to do anything smart with metathingies; it simply installs a wrapper for has that munges the attribute specification hash before passing it on to the original has function.
