+I don't know nemerle syntax, but this looks to me like you're creating
+a new instance of the Random object for each number. This won't work
+well as Random is initialized with the current time (in seconds
+granularity) as seed. So you'll get the same number for 1 second.
+The correct usage would be to create 1 random object and then reuse it
+for all numbers.
