## `Loop::run()`
The primary way an application interacts with the event reactor is to schedule events for execution and then simply let the program run. Once `Amp\Loop::run()` is invoked the event loop will run indefinitely until there are no watchable timer events, IO streams or signals remaining to watch. Long-running programs generally execute entirely inside the confines of a single `Amp\Loop::run()` call.

`Loop::run()` accepts an optional callback as first parameter. Passing such a callback is equivalent to calling `Loop::defer($callback)` and `Loop::run()` afterwards.
