17 MooseX::AlwaysCoerce - Automatically enable coercions for Moose attributes
25 our $VERSION = '0.07';
32 use MooseX::AlwaysCoerce;
33 use MyTypeLib 'SomeType';
35 has foo => (is => 'rw', isa => SomeType); # coerce => 1 automatically added
37 # same, MooseX::ClassAttribute is automatically applied
38 class_has bar => (is => 'rw', isa => SomeType);
42 Have you ever spent an hour or more trying to figure out "WTF, why did my
43 coercion not run?" only to find out that you forgot C<< coerce => 1 >> ?
45 Just load this module in your L<Moose> class and C<< coerce => 1 >> will be
46 enabled for every attribute and class attribute automatically.
48 Use C<< coerce => 0 >> to disable a coercion explicitly.
