Thanks. For some reason I hadn't thought to use

(fromIntegral x)::PortNumber

I guess I got stuck on the idea of constructing a PortNum directly and didn't think beyond that. (Maybe PortNum should really be an abstract type to force indirect construction...?)

I also think that a Num instance for PortNumber is not a good idea. How shall (+) and (*) be defined?
