Huh? What about the "environment"? I am not that familiar w/
Smalltalk, but I thought it didn't do the correct unwinding of
modifications to global state (unless the programmer wrote a lot of
code ensuring it happens correctly) during exception unwinding.
I've always thought of call/cc as more powerful because of that.. am I
incorrect?
