> I think we'd be open to fixing this when it doesn't compromise readability. Can you open a new issue with some particularly bad examples?

I wouldn't necessarily say that it's particularly bad, but see the discussion following https://github.com/pydata/xarray/pull/2922#issuecomment-601496897.

But as a user, being able to do operations in place (via `out` or otherwise) is extremely useful when dealing with large arrays under memory constraints.

This showed up in xskillscore as we were doing `np.clip(xarray object, min, min)`.

It lets you reuse memory you already have. In particular for a simple operation like clip, you can do it in-place: `da.clip(..., out=da.values)`. Very useful if you deal with lots of data and memory is a concern.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,879033384
