@filmor can you take a look at this one at least in principle?

I'm okay with this one, though for a slight backwards-compatibility I'd propose we add [Obsolete]public class PyScope : PyModule with both public constructors copied. Is there any particular reason why you renamed the file from pymodule to module? Matching the filename makes sense to me.

@filmor re: filename. Without renaming the file, diff is larger (that's because the file has more code from PyScope than from PyModule). Diff tools assume pyscope is deleted, and pymodule gets tons of new stuff. When file is renamed, they properly detect that is more a rename of pyscope with minor stuff from PyModule, then a rename of pymodule with minor stuff from PyScope.

@filmor re: PyScope. The original PyScope did not have any public constructors. E.g. there's no point in keeping it.

It had public static functions, though (and that's also how I always used it). So you can probably ignore the constructors, but deriving still makes sense.

@filmor I don't see any public static functions on old PyScope. There was a single factory method Py.Scope() and I preserved that one.
