Agreed - though [find] is one of the examples where you do need find and
find_exc - because often there are occasions where before calling
{Map,Set,Hashtbl}.find you already know that the key exists and so won't
fail at which point the 'a option boxing is a waste of time and space and
Not_found would be a truly exceptional situation so passes the previously
mentioned test.
