NAME
       Path::Dispatcher::Rule::Under - rules under a predicate

SYNOPSIS
	   my $ticket = Path::Dispatcher::Rule::Tokens->new(
	       tokens => [ 'ticket' ],
	       prefix => 1,
	   );

	   my $create = Path::Dispatcher::Rule::Tokens->new(
	       tokens => [ 'create' ],
	       block  => sub { create_ticket() },
	   );

	   my $delete = Path::Dispatcher::Rule::Tokens->new(
	       tokens => [ 'delete', qr/^d+$/ ],
	       block  => sub { delete_ticket(shift->pos(2)) },
	   );

	   my $rule = Path::Dispatcher::Rule::Under->new(
	       predicate => $ticket,
	       rules	 => [ $create, $delete ],
	   );

	   $rule->match("ticket create");
	   $rule->match("ticket delete 3");

DESCRIPTION
       Rules of this class have two-phase matching: if the predicate is matched, then the contained rules are matched. The benefit of this is less
       repetition of the predicate, both in terms of code and in matching it.

ATTRIBUTES
   predicate
       A rule (which must match prefixes) whose match determines whether the contained rules are considered. The leftover path of the predicate is
       used as the path for the contained rules.

   rules
       A list of rules that will be try to be matched only if the predicate is matched.
