tbuff is a recursive local function, so the symbol must be declared
before the definition. It helps to remember that 'local function f' is
short for 'local f = function' - so any reference to f in that
_anonymous_ function doesn't find the local because it's not defined

local tbuff
tbuff = function (t,buff,k)
  .-- refer to local tbuff!
