  You just need a Y-combinator:

	function Y(f)
	  local function g(...) return f(g,...) end
	  return g
	end

	print(Y(function(rec, x) 
			if x < 2 then 
				return 1 
			else 
				return x * rec(x-1) 
			end 
		end)(5))

  That will allow you to call an anonymous function recurively from within
the anonymous function.  No need for _SELF in this case.
