For those who are interested, here’s an updated version of the Python interop layer that I’m slowly pushing forward. This adopts conditional conformances, which cleans up the array/dictionary interop layer (they can now conform to PythonConvertible). This does not yet adopt @dynamicMemberLookup, as it is not supported in Xcode 9.3:

Questions, comments, suggestions for improvement welcome.
