Answer 1

Answering the question about plans for call/cc in Lua: There are no plans for call/cc in Lua. Capturing a continuation is either too expensive or require some code analsis well beyond what the Lua compiler can do. There is also the problem that Lua continuations may include parts in C.

With coroutines, however, we can already implement call/cc1 in Lua (one-shot continuations). That is good enough for many uses of continuations.
