Shall we have a GHC warning if it can detect those cases, either the
Haskell report bounds or that of the target GHC is currently compiling
to? (of course someone would have to implement it, and there would
always be cases it didn't check, and the (non-portable) behavior is
Hugs often does throw an exception (runtime error) rather than allow Int
overflow (but not always).
