You've just moved the problem along. There's now a new class of object that, if evaluated to, will be treated as if evaluation failed on exception. Successful evaluation can yield literally any value, so if you want to represent the disjunction of an evaluation result with something that's not an evaluation result then you can't have evaluation results just represented as themselves. That doesn't leave any distinct values to represent the other things. You need more structure: for example, your single $output value could be a list of the form (True, $value) to represent a normal evaluation result and (False, $ex) to represent evaluation terminating by exception. -zefram
