170 These methods are implemented in
171 Moose::Meta::Attribute::Native::MethodProvider::Bool. It is important to
172 note that all those methods do in place modification of the value stored in
176 Sets the value to \f(CW1\fR.
179 Set the value to \f(CW0\fR.
182 Toggles the value. If it's true, set to false, and vice versa.
185 Equivalent of 'not \f(CW$value\fR'.
