Depends on #2646 Right now, deduced parameter handling is very narrow to `self` support. This folds it into pattern handling, which should eventually be a superset of deduced parameter support, so this will avoid more duplication of logic. Note, this subtly adds handling of multiple deduced parameters, but not generic parameters (`:!`) so it's still not quite right.
