No plans to yield across ActionScript "frames" so far. Suggestions on
the form and on the implementation are welcome.

It is probably too much to ask anyway - ActionScript would need to be fundamentally different internally, I imagine.

What I really would like to be able to try is a program where a hosted Lua script uses coroutines in a simplistic way that demonstrates a Lua function suspending itself until later. For example, this:

  player:say("I shouldn't have eaten that.")
  player:say("I don't feel too good.")
  player:animate("die") a Lua script for some kind of (morbid) Flash adventure game. Each of these methods on the "player" (a Lua object, here, rather than a proxy to an ActionScript object) may internally use coroutine.yield() many times in order to "sleep" until the next step of the game (when the Flash application's timer event next fires).

It would most likely be var:function(param).
