Lightweight coroutines
We call a lightweight coroutine (or `lcr' for short) a function which does not return its result directly, but instead passes it to an extra *continuation* argument (often called 'continue' or 'cont'). Codinig with explicit contination arguments is a well-known technique, called continuation-passing style (CPS). CPS allows inversion of control to take place. Indeed the continuation may be installed as a callback, rather than being called directly. In general, any CPS function may yield control, and thus implement a lightweight form of concurrency. This module provides: - marcros which can translate direct-style code into cps - a library of lcr's to read from processes, wait some time, etc. Why use this module, instead of Emacs' built-in concurrency support? - for better control over context switch and/or scheduling - for versions of Emacs which do not provide concurrency
