I know this has been talked about before, and I read all the posts in the archive on this. There wasn't an "accepted" method for going about it, so I wondered if this implementation is optimal:

function execute(func, ...)
  return func(...);

function test(s)
  return execute(function(f)
    local fact;
    fact = function(n, ret)
      ret = ret or 1;
      if n == 0 then return 1 * ret end;
      return fact(n - 1, n * ret);
    return fact(f);
  end, s);

test(3) --> 6
