Wouldn't this deserve a longer (Dictionary comment) ?
You're right, the invariant is *essential* for Set and its subclasses, alas no word about it in its class comment. Please open a bug report (with severity "text"); current policy is that this then gets included in the next release.
Feel free to correct or complete http://bugs.squeak.org/view.php?id=6942
Maybe a reminder 'See also Set comment in Dictionary comment' would be welcome.
Cheers
