I am not sure what this answer that one, I think the llvm mailing lists would be much better able to answer your question.

There really arnt docs for anything like this so thanks to lldb/Expression/ClangExpressionParser.cpp I now know how to enable this feature. Can anyone point me to a usage of this? I'm not entirely sure how it should work and nothing stood out to me.
