32 This provides a simple boolean attribute, which supports most of the
33 basic math operations.
34
36 These methods are implemented in
37 MouseX::NativeTraits::MethodProvider::Bool. It is important to note
38 that all those methods do in place modification of the value stored in
39 the attribute.
40
41 set Sets the value to true.
42
43 unset
44 Set the value to false.
45
46 toggle
47 Toggles the value. If it's true, set to false, and vice versa.
48
49 not Equivalent of 'not $value'.
