Again IIRC, performance was an issue. I was trying to apply something like BinListsBy to very long lists. My implementation was never as performant as desired.

Have you done any performance assessments on BinListsBy?

I've wanted something like this for a long time too. It has been a while since I've needed it, but if I recall correctly, the application was a sliding window of fixed time-width across irregularly sampled data.

However, I think recent improvements in the TimeSeries subsystem have addressed my specific need.
