@Dennis I think at some point you talked about a planned TIO feature, namely supporting test suites (not manually via header and footer as is done now, but something more automatic). Are you planning to do that? (Or maybe I just got it wrong?) I'm asking because we are considering a modification in MATL to make it easier to do test suites with the current set-up, but it would be pointless to include it if TIO is going to support test suites automatically
