LGTM. Thanks for this. I'm okay with the approach of having a custom symbol visitor to differentiate between DEF and REF, and then using it to modify `symbolsInNestedRegion`. 

Such a symbol visitor could be a useful tool later on, and maybe we can eventually move it into `Utils.cpp` to share across different components. For now however, I think we can go ahead with the PR.
