=head1 ROLES VS TRAITS VS SUBCLASSES
-It is important to understand that B<roles and traits are the same
-thing>. A role can be used as a trait, and a trait is a role. The only
-thing that distinguishes the two is that a trait is packaged in a way
-that lets Moose resolve a short name to a class name. In other words,
-with a trait, the caller can refer to it by a short name like "Big",
-and Moose will resolve it to a class like
-C<MooseX::Embiggen::Meta::Attribute::Role::Big>.
