37/**
38 * ATException is the superclass of all exceptions thrown by the AmbientTalk interpreter. 
39 * 
40 * TODO tvcutsem Should NATException not implement the interface ATException, such
41 * that all of our code can be typed by 'throws ATException' clauses instead of
42 * 'throws NATException' clauses. The latter will cause problems with reflection.
43 * 
44 * TODO tvcutsem Shouldn't we parameterize NATExceptions with an ATContext and possibly
45 * also an ATAbstractGrammar for evaluation errors. This allows the user to inspect
46 * both which expression was evaluated at exception-raising-time and allows him to inspect
47 * the context at exception-raising-time.
