If I have this:

local t = {}
local another_function(wrapped, ...)
  print(t[wrapper])

local function wrap(something_important)
  local function wrapper(...)

  end
  t[wrapper] = something_important
  return wrapper
end

Is it guaranteed that 2 calls to wrap() won't cause weird fucked-up semantics? E.g. can I do this?

local wrap1 = wrap(1)
local wrap2 = wrap(2)
wrap1() --> prints 1
wrap2() --> prints 2

Yes, closure "wrapper" is guaranteed to be a new function every time.

Because this closure refers to local variable "wrapper" which is different every time.
