As far as I can tell, what happens is that with() thinks that it doesn't need
to generate a temporary variable because its expression is an lvalue, due to
the ref return. Since the expression *does* result in a temporary cleanup with
destructor, however, the destructor is inserted immediately after the with()
expression, instead of after the body.
