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();
innermost.SetVariable("somevalue", 3);
outermost.SetVariable("next", innermost);
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.
Thanks,
Marty Nelson
