Welcome

Description of the problem

I tried to use the new experiment feature Range-Over-Function in Go1.22.
I ensured GOEXPERIMENT is set correctly.

$ go env -w GOEXPERIMENT=rangefunc
$ go env GOEXPERIMENT              
rangefunc

I ensured the version of golangci-lint is latest.

go install github.com/golangci/golangci-lint/cmd/golangci-lint@latest

I can build the whole package successfully by go build.
But golangci-lint can't recognize it.

Version of golangci-lint

$ golangci-lint --version
golangci-lint has version v1.57.2 built with go1.22.0 X:rangefunc from (unknown, modified: ?, mod sum: "h1:NNhxfZyL5He1WWDrIvl1a4n5bvWZBcgAqBwlJAAgLTw=") on (unknown)

Configuration

By default, we don't support GOEXPERIMENT.

Even with the right way to compile and run golangci-lint with rangefunc, it's not supported by linters.
