]> [old thread resurrected] Actually, I spoke too soon below, you have to have the "as xy" on there to be able to reference the tuple by xy. Doesn't that seem redundant given the ?xy: specification (which doesn't seem to be used)? # let f ?xy:((x,y)=(0,0)) () = x + y;; val f : ?xy:int * int -> unit -> int = <fun> # let f ?xy:((x,y)=(0,0)) () = xy;; Characters 29-31: let f ?xy:((x,y)=(0,0)) () = xy;; ^^ Unbound value xy # let f ?xy:((x,y) as xy =(0,0)) () = xy;; val f : ?xy:int * int -> unit -> int * int = <fun> # let f ?xy:((x,y) as blah =(0,0)) () = blah;; val f : ?xy:int * int -> unit -> int * int = <fun> # Chris At 18:11 3/27/2003 -0800, Chris Hecker wrote: >James replied off list, but I thought the others might like to see it: > >At 17:35 3/27/2003 -0800, james woodyatt wrote: >># let f ?xy:(x,y as xy = 0.0,0.0) () = xy;; >>val f : ?xy:float * float -> unit -> float * float = <fun> > >Ah, that's what I wanted, thanks! It looks like you can just do ?xy:(x,y >= 0,0) and skip the "as xy" too.
