Comment (by jrf):

 > It would be good to handle, or at least anticipate union types and
 nullable types, based on PHP syntax (for instance ?int|string).

 I'm not sure this actually has merit as in the case of a multi-type input,
 the hooked in functions would need type checks anyhow, so what would be
 the benefits of using the new functions in that case ?
