[Haskell-beginners] Overflow when reading C types

[Patrick Redmond]

Yeah, the unsigned is to demonstrate how "-10" is being interpreted as a
number before being cast to an unsigned.

My question is: Why isn't this just a read/parse error? "-10" isn't a valid
representation for any value of the CUInt type.
