An exception breaks execution until caught/handled whereas conditions don't necessarily break execution, and are of more informational nature. What is described are exceptions (flow outside of the expected flow) yet thee should still be a condition based solution, perhaps using continuation mechanisms.

To my experience they are di= fferent things. An exception breaks execution until caught/handled whereas = conditions don't necessarily break execution, and are of more informati= onal nature. What is described are exceptions (flow outside of the expected= flow) yet thee should still be a condition based solution, perhaps using c= ontinuation mechanisms.
