The confusing part is that a function called 'put' actually deletes something, especially since we also have a 'delete' function. I would put the question this way: What problem are you trying to solve? If the problem is that people can't store "undefined" and then tell "undefined" apart from "not there" then your proposal doesn't solve that problem as "undefined" can't be stored at all. Additionally, as was mentioned, you can still tell "undefined" from "not there" by using a cursor. / Jonas
