AsyncCallable class abstract interface

An interface for functions and mixins that can be invoked from Sass by passing in arguments.

This class represents callables that need to do asynchronous work. It's only compatible with the asynchronous compile() methods. If a callback can work synchronously, it should be a Callable instead.

See Callable for more details.
