 =head1 DESCRIPTION
 
-Using this class to load Moose instead of just loading using Moose
-itself makes your constructors "strict". If your constructor is called
-with an attribute init argument that your class does not declare, then
-it calls "Carp::confess()". This is a great way to catch small typos.

+does not declare, then it calls "Carp::confess()". This is a great way
+to catch small typos.
 
 =head2 Subverting Strictness
 
-You may find yourself wanting to accept a parameter to the constructor
-that is not the name of an attribute.
-
-In that case, you'll probably be writing a C<BUILD()> method to deal
-with it. Your C<BUILD()> method will receive two parameters, the new
-object, and a hash reference of parameters passed to the constructor.
+You may find yourself wanting to have your constructor accept a
+parameter which does not correspond to an attribute.
 
-If you delete keys from this hash reference, then they will not be
-seen when this class does its checking.
+In that case, you'll probably also be writing a C<BUILD()> or
+C<BUILDARGS()> method to deal with that parameter. In a C<BUILDARGS()>
+method, you can simply make sure that this parameter is not included
+in the hash reference you return. Otherwise, in a C<BUILD()> method,
+you can delete it from the hash reference of parameters.
