27         $room->darken;         # same as $room->is_lit(0);
28         $room->flip_switch;    # same as $room->is_lit(not $room->is_lit);

DESCRIPTION

32       This provides a simple boolean attribute, which supports most of the
33       basic math operations.
34

PROVIDED METHODS

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'.
