Using @ with variable causes IDE crash

[jayrulez]

	public class Testing
	{
		public List<char8*> extensions = new .() ~ delete _;

		[Inline] public bool checkExtension(String @extensionToCheck)
		{
			return extensions.FindIndex(scope [&] (ext) =>
				{
					return String.Equals(ext, @extensionToCheck);
				}) != -1;
		}

	}

The code above causes the IDE to crash

This crash got fixed at some point, and now gives an actual error of Unable to capture 'extensionToCheck', but still doesn't actually work...
