title: @"" string type literals for NSNumber
body: <p>I love the shorthand handling of string literals in Objective C with the <code>@"string"</code> notation. Is there any way to get similar behavior with <code>NSNumber</code>s? I deal with numbers more and it's so tedious having <code>[NSNumber numberWithWhatever:]</code> calls everywhere. Even creating a macro would work, but my knowledge of how best to do that is limited.</p>
