 Zhivago whale: hmm, I think that you might be confused about what polymorphism means.whale: it is exactly like optional arguments. whaleofconfusion is there any way to have (values (values 1 2) (values 3 4)) be different from (values 1 2)? Zhivago whales: values doesn't work like that fax ayrnieu: btw I am stuck with my J interpreter ayrnieu fax - stuck where? Zhivago whales: values, like arguments, aren't first class fax ayrnieu: Im finding function application based on rank really complex..I think I just have to write more J and learn it betterive been reading about APL as well, I think its helped a little hefner (multiple-value-call #'values (values 1 2) (values 3 4)) ; don't do that. Zhivago whales: think of values like arguments, not like tuples whaleofconfusion I meant earlier, (values 1 3) not (values 1 2) action hefner boggles hefner boggles whaleofconfusion (values (values 1 2) (values 3 4)) is (values 1 3) not (values 1 2) as I said beforeit might be nice and would not break anything if (values (values 1 2) (values 3 4)) returned a 2 x 2 values matrix rahul oh my godwhaleofconfusion: stop it. please.how the hell would you make USE of that "matrix"? whaleofconfusion you're right there is no syntax to access anything except the first 2 values of the matrix rahul where is the "matrix" in parameters to functions? rudi no, please continue - what should (values (values 1 2) (values 3 4 'a)) do? rahul heh whaleofconfusion you would have to define that syntax hefner heh, (multiple-value-bind ((a b) (c d)) ...) whaleofconfusion that would work Zhivago whale: values aren't tupleswhale: just like arguments aren't tuples.whale: so, you might argue that calls should be done with tuples -- but that's a different conversation whaleofconfusion (values (values 1 2) (values 3 4 'a)) would return 2 values, each of which is itself 2 values, the first of which being the values 1 2 and the second of which being the values 1 2 'a Zhivago whales: values aren't objects -- you are wrong.whale: (+ 1 2 3) what is 1 2 3? whaleofconfusion three arguments Zhivago whale: what kind of object is three arguments? whaleofconfusion ah // the second of which being the values 3 4 'a rahul "//"? Zhivago whale: well? rahul oh, up there whaleofconfusion well it's not an object Zhivago whale: good.
