Okay, let me be more clear*: Bullshit. Link to your "sane Lua
implementation". Come on, let's see it. To my knowledge, no Lua
implementation uses linked lists for the function stack (not call
stack) and, even if they did, it wouldn't be useful anyway when
copying groups of values between coroutines.

* You know, your snide remarks don't help you at all here. There are
smart people on this list and if someone doesn't understand, it's
probably not because they're stupid. Maybe you just need to do a
better communicating what you know/think.
