Andreas Stührk <[email protected]> added the comment:
Another thing that can happen is that `__new__()` does return an instance of
BaseException, but that the return value is not an instance of the expected
class.
Example:
class MyException(OSError):
def __new__(*args):
return Exception()
try:
raise MyException
except OSError as e:
print(isinstance(e, OSError))
That would print "False". Currently, the patch doesn't check for that, should
it do so?
Also, the error message for the 2.7 patch doesn't include that old-style
classes are allowed, hence the patch needs to be updated if it should go into
2.7.
