Excellent to hear this confirmed. Out of curiosity, does it mean that
these "reusable" functions are globally pooled, a bit like strings, or
will it only apply to functions that came from exactly the same place?
For example:

  a = function()  return 5;  end
  b = function()  return 5;  end

...would a and b be the same, or different?
