...al reader APIs in ReaderWriter.h would have a member function on BitcodeReader. We would also have a next() member function which would move to the next module in the file. For example: BitcodeReader R(MBRef); Expected<bool> B = R.hasGlobalValueSummary(); std::unique_ptr<Module> M1 = R.getLazyModule(Ctx); // lazily load the first module R.next(); std::unique_ptr<Module> M2 = R.parseBitcodeFile(Ctx); // eagerly load the second module We'd continue to support the existing functional APIs in ReaderWriter.h for convenience in the common case where the bitcode file has a single module....

I rather see the bitcode reader...
