If an error happens in BoutOutputs.__init__() before self._parallel is defined, the exception message gets hidden behind one from __del__() saying AttributeError: 'BoutOutputs' object has no attribute '_parallel'. What's the 'correct' way to fix this? We could move self._parallel = parallel to the first line of __init__() and I guess that would fix this issue here, but it feels kludgy and non-general. Does anyone know of a nicer pattern?
For example, this happened in boutproject/BOUT-dev#2335 (comment)
