| 7.19.2. GHC's interpretation of undefined behaviour in Haskell 98
| This section documents GHC's take on various issues that are left

| Sized integral types
|    In GHC the Int type follows the size of an address on the host

|    machine, and 64-bits on a 64-bit machine.

Looks like a reasonable way to go about it.

If I haven't seen further, it is by standing in the footprints of giants
