If you do what you suggest, the following program crashes (and is well
typed *)
exception Found of 'a;;
let rec assoc_exn n = function
[] -> raise Not_found
| ((x,y)::l) ->
if x = n then raise Found y else assoc_exn n l
try
assoc_exn 1 [1,2]
with
Found x -> print_string x (* x will be an integer, not a string *)
