title: Does Go have a case-insensitive string contains() function?
body: <p>I would like to be able to determine whether stringB is a case-insensitive substring of stringA. Looking through Go's <code>strings</code> pkg, the closest I can get is <code>strings.Contains(strings.ToLower(stringA), strings.ToLower(stringB)</code>. Is there a less wordy alternative that I'm not seeing?</p>
