    `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:

<!-- iOS 10, macOS Sierra, and friends bring a new logging subsystem that's
supposed to scale from the kernel, up to frameworks, and up to apps. It defaults
to a more regimented, privacy-focused approach that large apps and complex
systems need.

It, along with Activity Tracing introduced in iOS 8 and macOS Yosemite and the
