The most important phenomena occur in the space between the objects, so
I don't think method annotations would help (since they apply to one
method at the time). <br>
<br>
The UML Sequence Diagram is often useful. It would be nice if it could
become either the program itself or a constraint. I have used it to
visualize the stack at a given point in an execution. It got too large
to be useful in the examples I tried, so I stick to the textual
version. You can find the very simple set of textual methods as part
of the BabySRE package. (Smalltalk Reverse Engineering)<br>
<br>
The methods are Object>traceRM:, stackSnapshotBrowseOnce:
levelCount, and others that can be found at my Monticello repository<br>

Which parts in 2.x do you find best for this?
Have you considered whether Squeak method annotations might bridge some of
the gap?

Squeak class hierarchy to UML diagram is easy; attributes and associations
are hard. To work typed UML <-> typeless Smalltalk code, you would need
either additional type annotations (e.g. pragmas on read-accessors) or type
inference (e.g. RoelTyper). Other UML diagrams might need additional
annotations.
There is a Connectors-based package languishing somewhere that lets you draw
some rudimentary UML in squeak itself. Dandelion, also languishing, does
some Squeak code analysis and exports XMI

Dynamically figuring things out from the instance-level would be a different
matter, specially if the tool was able to summarize certain information.
There is a nice ClassDiagrammer available that reconstructs a class diagram
from a set of instances, with a little work it could be very useful. A
sequence diagram generated from actual trace of method sends could also be
very useful. If you prefer to diagram first, then some of these diagrams
could conceivably become inputs to tests.
