Maybe rename this file? Didn't Siggi change the naming convention for these
files recently?

Not sure I understand line 4 here. Get rid of it?

Update comment.

[karlklose, 2012/05/01 11:20:55]

Done, removed.

+class Hest<X> {}
+
+main() {
+  var x = new Hest<int>();
+  Expect.isTrue(x is Hest<int>);

[kasperl, 2012/04/30 08:48:32]

So would 'x is Hest<num>', 'x is Hest<Object>', 'x is Hest<Dynamic>' or 'x is
Hest' work? Maybe add them if they already work.

[karlklose, 2012/05/01 11:20:55]

It does not work currently. 

+  Expect.isFalse(x is Hest<String>);
