Return AsObservable Enum

Introduction I was sitting around trying to recall WPF-related programming problems I had over the years, and remembered one involving creating observable collections of enumerator values. This happened to me long ago, and I can't find the code where I resolved the issue, but I do remebmer that it was specific to the enumerator involved, and that's actually a "bad thing" (TM). This article presents a debuggable generic approach, and should work for any enumerator you might decide is important.
