Awesome. I will thanks.

This might be possible. If you wrap this all up in a PythonAst object

But it’s not like this is well traveled territory and this only applies to
2.6.1 (before that the trees weren’t DLR ASTs so they weren’t reducable).
When we do this ourselves we also call the produced delegate and flow in
some data. The delegate is going to want at least a FunctionCode object as
an argument but I think you could get away with passing null (at least as
long as no exceptions are thrown). The delegate might also want a
CodeContext object as well depending on the compilation mode we end up using
(which is based on the CompilerContext you give us). This you wouldn’t be
able to get away w/ passing null. But you can get one by doing new
ModuleContext(new PythonDictionary(), pythonContext).GlobalContext. The
HostingHelpers class can give you a LanguageContext from the ScriptEngine
for Python which you can cast to a PythonContext.
Let me know if it works! J
