       If you don't provide an "isa" value for your attribute, it will default to "Bool".

       This trait provides native delegation methods for boolean values. A boolean is a scalar which can be 1,
       0, "", or "undef".

       None of these methods accept arguments.

       •   set

           Sets the value to 1 and returns 1.

       •   unset

           Set the value to 0 and returns 0.

       •   toggle

           Toggles the value. If it's true, set to false, and vice versa.

           Returns the new value.

       •   not

           Equivalent of 'not $value'.
