Thanks, makes sense. I wonder if there's a tool to find the old code pattern. We've switched to slices.Contains in many places, but missed this one.

I also search by keywords, and there will be a lot of omissions. But I think I can write such a tool

I did something with semgrep and found these:

Oh, the one you found can't be changed. That accountsList is a map, not a slice.

My semgrep rule had the same issue. I fixed that, so there are only 5 detected now, instead of 11.

[jannotti]

To remove approval, I have to comment. Issue is the map vs slice thing.

Great job. I'll modify the other items you found.

Everything else has been modified, I will keep an eye on ci.

But I feel like these are

Since there is no return false operation, it may not be possible to use slice.Contains optimization.
