|
|
|
|
|
|
|
|
55
|
|
|
|
|
|
|
This trait provides native delegation methods for boolean values. A boolean is |
56
|
|
|
|
|
|
|
a scalar which can be C<1>, C<0>, C<"">, or C<undef>. |

=head1 DEFAULT TYPE |
59
|
|
|
|
|
|
|
|
60
|
|
|
|
|
|
|
If you don't provide an C<isa> value for your attribute, it will default to |
61
|
|
|
|
|
|
|
C<Bool>. |
