But for that, it's fine to sort when you are doing the comparing / serialization. What I haven't been able to imagine is a use case for keeping a Mapping sorted constantly as you insert / remove items. For that you'd need a use case where you were making sorted queries of various sorts. I noticed, for instance, that the Java implementation posted earlier had methods like "all the items after this one" (can't remember how that was spelled). I'm sure there are use cases for this, I'm probably lacking imagination :-) -CHB -- Christopher Barker, PhD (Chris) Python Language Consulting - Teaching - Scientific Software Development - Desktop GUI and Web Development - wxPython, numpy, scipy, Cython
