ScriptScope objects. The DLR APIs are separated into two halves - the hosting
API half and the language API half. The hosting API objects are all remotable
and expose the APIs which are needed for hosting. The language API half are
all appdomain bound and expose the API that language implementers need to see.
IronPython actually adds extension methods to both ScriptScope and Scope so
they both work like modules but Scope has more functionality such as a correct
__repr__, __new__, etc...
You can either new up a Scope object directly or if you have a ScriptScope you
can call HostingHelpers.GetScope.
:-)
ScriptScopes are more convenient to work with, so I'll turn them into a
Scope when I publish them onto the runtime.
Thanks

Bah, damn - I meant to try that before posting and then forgot!
Hmmm... although from inside Python code run in the engine you can still
tell that it is a ScriptScope and not a 'real' module. I'm pretty sure
that internally IronPython *is* using PythonModule.
Not that it is a problem, publishing ScriptScopes works fine - it would
be *nice* to have access to the same API that IP uses for publishing
modules, but not essential.

The name PythonModule is unfortunately a little confusing - it's
actually a PythonScopeExtension where we can store additional data
about the Scope (e.g. if import clr has occurred). We'll lazily
create the PythonModule and associate it with the Scope if we need it.

Subject: [IronPython] Publishing a Module when Embedding
Hello all,
I've been looking at writing some examples of publishing a module in an
embedded scenario.
The straightforward example (which also appears in the DLR hosting spec)
is to just publish an *object*:
ScriptRuntime _runtime = ScriptRuntime.Create();
_runtime.Globals.SetVariable("ModuleName", someObject);
What I *really* want to do is to create a PythonModule from a dictionary
of objects and publish that into the runtime globals.
Creating a populated PythonModule seems to be problematic. The useful
overload of PythonCOntext.CreateModule (that takes 4 arguments) isn't
public (internal) - I can't see how to populate the module once I've
created one.
There is also an internal constructor to PythonModule that takes a
Scope. These seem to be the routes taken by the importer.
You can't publish a dictionary (well - except as a dictionary).
How can I create and populate a PythonModule from C#?
