Until 5.00 I could use mkPortNumber to get what I want, i.e. PortNumber (mkPortNumber port) Now in 5.01, this function now longer exists. (PortNumber 5) works, but (PortNumber (5::Int)) does not, so I have to use "fromIntegral" to get it to work again: PortNumber (fromIntegral (5::Int)) I suppose I'm missing something essential here, as there must be a better way of doing it when passing a variable of type Int. -- Abstrakte Syntaxträume.
