Given the explicit wording in the standard it appears to me that the
implementations are non-conforming, perhaps for historical reasons.
> 2. Is this a deliberate change to make #peekFor: only do peeking?
It looks that way to me. Perhaps someone who was on the committee could
clarify this.
> 3. Is this something Squeak and VAST have changed?
These implementations almost certainly pre-date the standard.
> 4. Do other Smalltalks do the same as Squeak?
VisualWorks and Dolphin Smalltalk implement peekFor: in the same way as
Squeak.
