  35. * ATException is the superclass of all exceptions thrown by the AmbientTalk interpreter.

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