block => sub {
my $match = shift;
attack($match->pos(2))
},
);

# introspection
$match->path # "attack dragon"
$match->leftover # empty string (populated with prefix rules)
$match->rule # $rule

parent
The parent match object, if applicable (which may be set if this match is the child of, for exampl, a Path::Dispatcher::Rule::Under prefix)
METHODS
