[Haskell-cafe] Bug in Network package

[Thomas DuBuisson]

Replying to all.  Sorry for the duplicate, Florian.

The fact that the constructor `PortNum` is exported has been argued to be a
bug in past discussions.  PortNumber is stored big endian, which leads to
behaviors that people don't expect.  I suggest you lean on the fact that
PortNumber is an instance of the Num class:

ghci
...
> 478 :: PortNumber
478

Cheers,
Thomas
