The "advice" feature lets you add to the existing definition of a function, by wrapping around the original function a "piece of advice".

Each piece of advice receives the original function and arguments; its result is returned to the caller as if from the original function.

A function may have multiple pieces of advice, which are composed by nesting earlier advice within later advice.
