Talk:Undefined values

After discussion on IRC, it was noted that "undefined" as this task is not significantly disctinct from NULL. However, I prefer this task's "identify and exercise the mechanisms" approach, as opposed to NULL's more specific "check" approach. I'm certainly open to other's thoughts on how to effect improvement of the NULL task, make this task sufficiently distinct, or possibly deprecate that task. --Michael Mol 03:04, 28 November 2009 (UTC)
