@cwebber @KitRedgrave I managed hack something like co-routines in by abusing self-modifying eval code. For a while in chrome could be tricked into spawning sub processes that communicated with the main thread via shared-webworkers. it was a nightmare of monkeypatching+AOP that ended up acting similarly to how yeild converts a python function into a generator object.

It was ran via a statemachine that would self-modify the functions by reasigning new function on the fly.
