There are better (more general but more complex) solutions.
First, you can do function composition :


function a(f)
  return function(x)
	return f(x) .. "a"
  end
end

function b(f)
  return function(x)
	return f(x) .. "b"
  end
end

f=b(a(function(x) return x end))

print(f"t")

Or you can use coroutines to implement filters.

Note: in both cases, the processing will be done sequentially, not
simultaneously in multiple cores.
If you really need multi-threading, you will need to deal with native
OS threads.
