[IronPython] How to nest ScriptScopes

It's not really intended that you nest the scopes yourself - usually the scopes only get nested when you have a closure. And then we'll burn references into the parent scopes tuple's directly so we might not even see nested variables (although in some cases we might due a full runtime lookup and see them).
Instead of nesting them can you have a ScriptScope that contains other ScriptScope's? In other words your inner most level is just a collection of ScriptScope's which you publish under some well known name into the outer level. Then users can dot through them:
outermost = new ScriptScope();
innermost = new ScriptScope();
then run in outermost.

Subject: [IronPython] How to nest ScriptScopes
I've gone over the 2.0 B2 source code, but I'm not clear how I might create nested ScriptScopes using the API in C#
One of the tests in EngineTests.cs uses "from published_context_test import x" but this is only one variable, and I'd rather do it from the C# setup side anyway.
I noticed that Scope, which ScriptScope contains, has the ability to take a parent Scope, but I'm not clear how I would do this. It seems not to be exposed via ScriptScope.
We are using IronPython as a script based extension mechanism for our C# application, my interest is to have a set of established scopes that I can populate with the variables of current application objects at the appropriate level for the current script.
