35 | has foo => (is => 'rw', isa => SomeType); # coerce => 1 automatically added |
36 | |

40 | =head1 DESCRIPTION |
41 | |
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 >> ? |
44 | |
45 | Just load this module in your L<Moose> class and C<< coerce => 1 >> will be |
2429fb7e |
46 | enabled for every attribute and class attribute automatically. |
ad1917d7 |
47 | |
44b44091 |
48 | Use C<< coerce => 0 >> to disable a coercion explicitly. |
