Comment (by Simon Charette):
Exceptions within `__del__` are effectively turned into stdout messages
and not raised but elevating them to errors make messages way more useful
and explicit about their origin
e.g.
{{{#!python
warnings.filterwarnings('error', 'unclosed', ResourceWarning)
}}}
Revealed a ton of other wise silenced messages of the following form when
running the suite of a large Django project
{{{
ResourceWarning: unclosed file <_io.TextIOWrapper name='path-to-file.json'
mode='r' encoding='UTF-8'>
}}}
