> Summary: removeAll: aCollection doesn't do what we
> expect if
> aCollection==self
> Description:
> This known error has had a revival originating from a mail of Sophie in

> The problem is:

> col := #(1 2 3) asOrderedCollection.
> col removeAll: col.
> ^col returns an OrderedCollection(2) instead of an empty one as we
> would
> expect...
