Description Alexander Köplinger 2015-02-27 20:59:26 UTC
Repro code:

>using System;
>
>public static class Test {
>	public static void Main() {
>		RunTest(() => Console.WriteLine($"Initializing the map took {1}ms"));
>	}
>
>	static void RunTest(Action callback) {
>		callback();
>	}
>}

This fails during compilation:
