StopIteration passtrough not handled correctly #544
Description
cpython impl ref in contextmanager
a test in one of my testsuites failed with a StopIteration as exception
this ran into issues as new style hook wrappers dont manage the RuntimeError of stopIteration
>>> def mygen(): yield
...
>>> gen = mygen()
>>> next(gen)
>>> e = StopIteration()
>>> try:
... gen.throw(e)
... except Exception as err:
... runtime = err
...
>>> runtime
RuntimeError('generator raised StopIteration')
>>> runtime.
runtime.add_note( runtime.args runtime.with_traceback(
>>> runtime.a
runtime.add_note( runtime.args
>>> runtime.args
('generator raised StopIteration',)
>>> runtime.__cause__
StopIteration()
>>> runtime.__cause__ is e
True
>>>
