Looks great! It works well so far from my testing. It also seems to
fix the problem of proceeding from stuff like "3 + (nil ifTrue: [2]
ifFalse: [3])". I hope that this and your other improvements will
eventually wander into the base image.
If you're still looking for debugger-related enhancement ideas... :)
One thing discussed on the list awhile back, which I think is a great
idea, would be to add a "debug it" to the main text menu after "do
it"/"print it"/"inspect it". Doing a "debug it" on a highlighted code
snippet would ideally bring up the debugger (skipping the notifier) with
the UndefinedObject>>DoIt frame pre-selected and the first message in
the snippet highlighted, ready to be sent/stepped.
This would be convenient for experts and beginners alike for quickly
stepping though code snippets, but would especially encourage beginners
to play with stepping through code in the debugger, which is one of the
best ways to learn Smalltalk. (I briefly tried to implement "debug it"
myself once, but I ran into some problem with getting at the current
context... I don't remember now. :) )
