SYNOPSIS
my $rule = Path::Dispatcher::Rule::Tokens->new(
tokens => [ 'attack', qr/^w+$/ ],
block => sub {
my $match = shift;
attack($match->pos(2))
},
);
my $match = $rule->match("attack dragon");
# introspection
$match->path # "attack dragon"
$match->leftover # empty string (populated with prefix rules)
$match->rule # $rule
