This should be new List<Match>()

   var length = receiver.length;
   if (length === 0) {
-    return result;
+    return [receiver];

receiver being a string and the returned type of that method being a List of
Match, I'm not sure how this can be right.

[Lasse Reichstein Nielsen, 2012/03/25 18:22:41]

Is [receiver] a Match object? Because it seems we are returning a list of Match
objects below.
