Quick benchmark taking the example in #7376 (it seems even much faster than in version 2022.3.0!)

```python

version 2022.3.0

%timeit ds.assign(foo=~ds["d3"])

22.5 ms ± 1.96 ms per loop (mean ± std. dev. of 7 runs, 100 loops each)

main branch

%timeit ds.assign(foo=~ds["d3"])

193 ms ± 1.35 ms per loop (mean ± std. dev. of 7 runs, 1 loop each)

this PR

%timeit ds.assign(foo=~ds["d3"])

1.01 ms ± 10.7 µs per loop (mean ± std. dev. of 7 runs, 1,000 loops each)

```
