No, but you can tell it to specialise a function to a particular type
(or any finite number of types), and it will automatically use the
specialised one if available.

(You can't automatically specialise in general if you're doing
separate compilation - well, you could, but it wouldn't really be
separate compilation, it would be more like using the function as a
macro).
