What

errcheck intentionally warns on defer statements, but sadly a lot of idiomatic code uses un-checked defer calls, e.g.

	resp, err := httpClient.PostForm(ts.URL+"/login/", params)
	if err != nil {
		t.Fatal(err)
	}
	defer resp.Body.Close() // This is not a thing you should need to error-check!

So errcheck lets you exclude function definitions in its invocation, like so: errcheck -exclude go_errcheck_excludes.txtn ./ (where go_errcheck_excludes.txt is the file below).

Drawbacks

Sadly, due to errcheck#132, it doesn't support the ReadCloser's Close method, so you have to reach for the much wider Closer's Close. I think that's an OK trade-off to make, but your preferences might vary.
