blocks:

• SR-377 Implement NSKeyed[Un]Archiver

relates to:

• SR-381 API to lookup a Type given a top-level class name

Issue Description:

typealias TypeMetadataAccessor = @convention(c) () -> AnyClass?

assert fails in ExistentialMetatypeType::ExistentialMetatypeType() at:

   assert(getASTContext().LangOpts.EnableObjCInterop ||
          *repr != MetatypeRepresentation::ObjC);

Commenting this out works but a correct fix is desired. This is only an issue on Linux.

If [SR-381] is resolved this bug can be closed

I'm going to close this as I agree with @jckarter that it's not valid behaviour for the non-ObjC build.
