Exceptions and Exception Handling
- during content generation, exceptions may be raised
- all exceptions are caught implicitely and undefined (the empty result) is returned
- queries can detect this and provide alternative behavior (exception handling
.....return some_function_which_may_crash() or else "currently our Windows server went up in smoke"
- any number of these clauses can appear in a return clause
- they are executed in a cascade, in text order
