// ## $.withAdvice
//
// Borrowed by [Flight](https://github.com/flightjs/flight).
//
// `withAdvice` is a mixin that defines `before`, `after` and `around` methods.
//
// These can be used to modify existing functions by adding custom code. All
// components have advice mixed in to their prototype so that mixins can augment
// existing functions without requiring knowledge of the original
// implementation.
