  Log Message:
  -----------
  add 'peek_exception' op as workaround for pct relying on .get_results to get the exception

.get_results clears the call object, so we cannot use it to get the exception
when HLL code also relies on .get_results returning the exception. Thus, the
new op returns the exception without clearing the call object. This op can
be removed again if PCT provides a different mechanism to get the exception and
all HLLs use the new mechanism.
