Stack-allocated views are a big deal! Even in code where the direct cost of the view allocations is acceptable (e.g. because the work per view is high), they should help a lot. Unnecessary allocations are one of the easiest way to accidentally mess up performance in Julia, but having all the views allocated made it much harder to find “problematic” allocations that scale with the problem size. Now it should be more realistic to aim for zero allocations in performance-critical code without giving up the nice ergonomics of views.
