Please ignore my last mail...
@OP: Only recently there has been a discussion on sorting, with implementations, you might want to have a look at it.
@Rafael:
- class Foo; @words; ... doesn't make any sense
- begin ... end while ... -> while ... end
- modifying a collection while iterating over it might lead to unexpected behavior (though prob. not in this case)
No time for more comments...
