=head1 NAME
 
Patterns::ChainOfResponsibility::Provider - The Provider Dispatch Strategy

=head1 DESCRIPTION

Dispatch @args to each Handler in turn until we find one that processes them.
This is probably the most classic "CoR" behavior.

You won't use this class directly.
Please see L<Patterns::ChainOfResponsibility::Role::Handler>
