NAME

       Test2::Compare::Negatable - Poor mans 'role' for compare objects that can be negated.

DESCRIPTION

       Using this package inside an Test2::Compare::Base subclass will overload "!$obj" and
       import "clone_negate()" and "toggle_negate()".

WHY?

       Until perl 5.18 the 'fallback' parameter to overload would not be inherited, so we cannot
       use inheritance for the behavior we actually want. This module works around the problem by
       emulating the "use overload" call we want for each consumer class.

ATTRIBUTES

       $bool = $obj->negate
       $obj->set_negate($bool)
       $attr = NEGATE()
           The NEGATE attribute will be added via Test2::Util::HashBase.

METHODS

       $clone = $obj->clone_negate()
           Create a shallow copy of the object, and call "toggle_negate" on it.

       $obj->toggle_negate()
           Toggle the negate attribute. If the attribute was on it will now be off, if it was off
           it will now be on.
