When checking the specific procedures of a generic interface for a match against a given set of actual arguments, be sure to not match a function against a subroutine call or vice versa. (We generally catch and warn about attempts to declare mixed interfaces, but they are usually conforming and can be inadvertently created when generics are merged due to USE and host association.)
