I don't think Squeak debugger has this feature or something similar (I could
VAST debugger provides a similar feature in that you can restart a selected
stack frame in your execution stack. All the temporaries within the
selected method context are completely reset. In other words, during
debugging, you can select an arbitrary point to restart (e.g. go back to a
frame that has been executed) and restart it with a 'clean' environment.
This is an extremely useful feature in my (and I guess to many) everyday work.
