=head1 SYNOPSIS
package MyClass;
use Moose;
- use MooseX::ClassAttribute;
use MooseX::AlwaysCoerce;
use MyTypeLib 'SomeType';
has foo => (is => 'rw', isa => SomeType); # coerce => 1 automatically added
- # same, but you must load MooseX::ClassAttribute *BEFORE*
- # MooseX::AlwaysCoerce
+ # same, MooseX::ClassAttribute is automatically applied
class_has bar => (is => 'rw', isa => SomeType);
=head1 DESCRIPTION
coercion not run?" only to find out that you forgot C<< coerce => 1 >> ?
Just load this module in your L<Moose> class and C<< coerce => 1 >> will be
-enabled for every attribute automatically.
+enabled for every attribute and class attribute automatically.
+
+Use C<< coerce => 0 >> to disable a coercion explicitly.
