NAME

       MooseX::StrictConstructor::Trait::Class - A role to make immutable constructors strict

DESCRIPTION

       This role simply wraps "_inline_BUILDALL()" (from "Moose::Meta::Class") so that immutable classes have a strict constructor.

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} ) {
		 ...
	     }
	 }
