Subject: [Caml-list] kprintf question (was printf question)
hi,

I've got three questions about Printf.kprintf :

 * why has it type
	(string -> string) -> ('a, unit, string) format -> 'a
and not 
	(string -> 'b) -> ('a, unit, 'b) format -> 'a

this would allow to make _exactly_ what we want within the
continuation.


* why is it _pseudo_ polymorphic ?
# Printf.kprintf (fun s -> prerr_endline s; "");;
- : ('_a, unit, string) format -> '_a = <fun>


* couldn't Printf export a dummy function 
	zprintf: ('a, 'b, unit) format -> 'a 
that does nothing !
this would allow a more efficient debugging function in the code I've
just posted (printf question), without inserting ugly Obj.magics.


thanks,
damien
