Detect when copied and original variable is used

[SuperSandro2000]

I have the following code which I extracted from a test:

		for _, req := range testRequests {
			failingReq := req // <----- here
			failingReq.ExpectBody = test.ErrorCode(keppel.ErrTooManyRequests)
			failingReq.ExpectStatus = http.StatusTooManyRequests
			failingReq.Check(t, h)

			s.Clock.StepBy(time.Second)
			req.Check(t, h)
		}

req gets copied and modified and both are used. I think the linter should ignore this or at least add an option to ignore it.

I apologize for the delayed response.
This linter has ignore-alias option. Have you tried it?👀

cf. https://golangci-lint.run/usage/linters/#copyloopvar

    ignore-alias: true
