At first, it was not asked before, so that's the reason it's not in IO.
A reason I can see now not to add it is that will link the whole Scanf
module ( 32 Ko ) just for this function as soon as you use IO.

You can simply use the following :

let io_scanf ch = Scanf.bscanf (Scanf.Scanbuf.from_function (fun() ->
IO.read ch))
