* Improve label mismatch callback: - Split "missing label" callback into 3 - missing, extraneous, incorrect (with typo(s)); - Allow label callbacks to indicate if it's a fatal error or not; * Improve matching of the variadic parameters; * Improve matching of the parameters with defaults; * Try to look for an argument with matching label before fallback to forced claming (if allowed).
