33 use MooseX::StrictConstructor;
39 # this blows up because color is not a known attribute
40 My::Class->new( size => 5, color => 'blue' );
44 Simply loading this module makes your constructors "strict". If your
45 constructor is called with an attribute init argument that your class
46 does not declare, then it calls "Carp::confess()". This is a great way
49 =head2 Subverting Strictness
51 You may find yourself wanting to have your constructor accept a
52 parameter which does not correspond to an attribute.
54 In that case, you'll probably also be writing a C<BUILD()> or
55 C<BUILDARGS()> method to deal with that parameter. In a C<BUILDARGS()>
56 method, you can simply make sure that this parameter is not included
57 in the hash reference you return. Otherwise, in a C<BUILD()> method,
58 you can delete it from the hash reference of parameters.
