[IronPython] hosting and SetVariable

[Slide]

Thanks that will be helpful. Is there any documentation specific to
IronPython? I would like to do some introspection on modules and such
(to retrieve types defined in the module and so forth) and I used to
do that with some PythonType magic which doesn't seem to work anymore
(ScriptScope is not convertable to Scope when calling Get__dict__).

Thanks again!
