 =head1 DESCRIPTION
 
-This provides a simple boolean attribute, which supports most of the
-basic math operations.
-
-=head1 METHODS
-
-=over 4
-
-=item B<meta>
-
-=item B<method_constructors>
+This trait provides native delegation methods for boolean values. A boolean is
+a scalar which can be C<1>, C<0>, C<"">, or C<undef>.
 
-=item B<has_method_provider>
+=head1 DEFAULT TYPE
 
-=item B<method_provider>
-
-=back
+If you don't provide an C<isa> value for your attribute, it will default to
+C<Bool>.
 
 =head1 PROVIDED METHODS
 
-It is important to note that all those methods do in place
-modification of the value stored in the attribute.
+None of these methods accept arguments.

-=item I<set>

+Sets the value to C<1> and returns C<1>.
 
-Sets the value to C<1>.
+=item * B<unset>
 
-=item I<unset>
+Set the value to C<0> and returns C<0>.
 
-Set the value to C<0>.
+=item * B<toggle>
 
-=item I<toggle>
+Toggles the value. If it's true, set to false, and vice versa.
