NAME
       MooseX::StrictConstructor - Make your object constructors blow up on unknown attributes

VERSION
       version 0.19

SYNOPSIS
           package My::Class;

           use Moose;
           use MooseX::StrictConstructor;

           has 'size' => ...;

           # then later ...

           # this blows up because color is not a known attribute
           My::Class->new( size => 5, color => 'blue' );

DESCRIPTION
       Simply loading this module makes your constructors "strict". If your constructor is called
       with an attribute init argument that your class does not declare, then it calls
       "Moose->throw_error()". This is a great way to catch small typos.

   Subverting Strictness
       You may find yourself wanting to have your constructor accept a parameter which does not
       correspond to an attribute.

       In that case, you'll probably also be writing a "BUILD()" or "BUILDARGS()" method to deal
       with that parameter. In a "BUILDARGS()" method, you can simply make sure that this
       parameter is not included in the hash reference you return. Otherwise, in a "BUILD()"
       method, you can delete it from the hash reference of parameters.

         sub BUILD {
             my $self   = shift;
             my $params = shift;

             if ( delete $params->{do_something} ) {
                 ...
             }
         }
