I stand corrected (although object seems like the wrong word, given that there are no methods on it. You can't do "my_thread:status()", although that's not a horrible idea, so long as threads could also have their metatable individually re-assigned)

I think that my confussion lies in the _expression_ of the feature as "coroutines" and the fact that there aren't any of those in Lua. There are functions, threads, etc.

I do not suggest any changes here (except for the change to the error reported by status). 

But, it does remind me of tables and the __index metamethod pointing to a table with string keys pointing at function values. We may call them objects, but Lua only knows about tables. (Accepting table:method()).
