A mechanism is proposed for binding exception handlers to exceptions. Hierarchical exception classes can be defined and changed during program execution. In addition, the action taken when an exception of a particular class is raised depends upon the type of the current exception handler for that class. The mechanism can be implemented in programming languages that allow runtime determination of an identifier's binding; most dynamically scoped programming languages meet this criterion.
