RE: Is this a scoping issue?

[jdarling@...]

Oddly enough though, in another article it shows the following code:

local thread_id = 0
local threads = {}

function fn(thread)
    thread_id = thread_id + 1
    threads[thread_id] = function()
                             thread = nil
                         end
    coroutine.yield()
end

while true do
    local thread = coroutine.create(fn)
    coroutine.resume(thread, thread)
end

So I'm confused and obviously haven't played with co-routines at all :)
