| `arc4random_uniform` is very useful but limited to `UInt32`. | |
| This defines a generic version of `arc4random` for any type | |
| expressible by an integer literal, and extends some numeric | |
| types with a `random` method that mitigates for modulo bias | |
| in the same manner as `arc4random`. | |
| `lower` is inclusive and `upper` is exclusive, thus: | |
