How to: [⏫](#contents) Replace symbol with `gofmt`
I found this in announcement [notice](https://github.com/golang/go/commit/2580d0e08d5e9f979b943758d3c49877fb2324cb) of Go 1.18 for changes to `interface{}` to `any`. This can be useful for other refactorings too.

```
gofmt -w -r 'interface{} -> any' .
```
