When Router is dispatching to a route's callbacks, it URL-decodes the matching path segments so that placeholders like
req.foo
don't have encoded values. Since Router supports registering a route as a Regex, when Router executes that regex it may return an array with some undefined matches. This fixes the issue where Router assumed all items in the array returned fromexec()
are strings.TODOs
