Re: Question regarding coroutines

your function has 'a' defined as a global. change it to 'local a = ...' and you get what you expect

It seems, that LUA uses the same memory to store the variable 'a' for
both coroutines
Is this a feature, is it a bug and how can i avoid it?
Can i not somehow 'duplicate' the function prior to resuming it?
