I would strongly advise against this. Firstly, exceptions are conceptually a
way to indicate a condition that is... exceptional! So in that sense it's
confusing. But maybe more importantly, I've encountered several areas in
Pharo where exceptions were hijacked in this way and it led to lots of pain.
The one that comes to mind first is the mechanism to show progress during a
long operation. Because exceptions were used inappropriately, only one
interested party would be notified, and then they would swallow the
exception. The appropriate technique in that case was an observer pattern,
now implemented with announcements. I encourage you to find a corresponding
pattern!
