such as loop unrolling.
Similarly, `krt` can make complex optimizations in one place, so each controller implementation doesn't, which is likely to increase
the amount of optimizations applied.

The `BenchmarkControllers` puts this to the test, comparing an *ideal* hand-written controller to one written in `krt`.
While the numbers are likely to change over time, at the time of writing the overhead for `krt` is roughly 10%:
