@peekay123 and @estrauss, I have added some hints in the above respect to @harrisonhjones 's repo and filed a Pull Request.
Maybe till then, you want to have a look at the changes at
https://github.com/ScruffR/Spark-Ported-Libraries
If you have any more quick suggestions, I’d try to work them in and do another PR.
Just seen that Harrison has already merged my PR
