first_argument_type/second_argument_type only exist for 2 argument signals. 1 argument signals just have argument_type. IIRC, thats how stuff in the functors in the STL look.
Oh, I see. Actually, I missinterpreted its description - I thought that first_argument_type should exist if the signal has *at least* 1 argument. Thanks again.
