| Exceptions historically derive from a single-threaded, imperative model of computation. Rather than including tests for the success of subsidiary operations at every procedure level using if-then-else's, it was deemed simpler to describe problems only where they arise and where they are dealt with. The catch-throw style was transferred to C++ (and then Java), and also grafted onto the I/O structures of declarative languages such as Prolog and Haskell. However, the evolution from object-oriented to event-oriented programming and the blending of this with a declarative base has led to a rather different view of computation, one which raises new questions about the relationships among events, exceptions and interrupts. This paper looks at some of these. |
