Message-ID: <199901201042.KAA01535@msc2.comlab> (raw)
If this works as it should:
> Objective Caml version 2.00
>
> # type foo =
> Bar of int * int;;
> type foo = | Bar of int * int
> # let myfun x =
> let (m,n) = if x = 0 then (0,0) else (1,1) in
> Bar (m,n);;
> val myfun : int -> foo = <fun>
then why doesn't this?
> # let myfun2 x =
> let m = if x = 0 then (0,0) else (1,1) in
> Bar m;;
> The constructor Bar expects 2 argument(s),
> but is here applied to 1 argument(s)
or even this?
> # let myfun3 x =
> Bar (if x = 0 then (0,0) else (1,1));;
> The constructor Bar expects 2 argument(s),
> but is here applied to 1 argument(s)
Thanks,
Chris.
