--- Comment #4 from Florian Schornbaum <florian.schornbaum at siemens dot com> --- Hi Jakub, Richard, I hope you both had a good start into 2019. I'm still wondering if there are any plans to make arbitrary index data types work with gather/scatter? If there are no such plans at the moment, we will work around this issue on our side.
