Ok, so we left to right insertion combined with right to left evaluation. That might be "algorithmically interesting" but it also seems unnecessarily complex for some useful cases.
Do we have no way of performing the insertion in the same order as the evaluation order? This would be important in constructing efficient gerund scans. And, currently, I'm not seeing any such option - given left to right insertion, we would need left to right evaluation of the insertion for an efficient scan.
