Summary
Previously the module of this was set incorrectly (stemming from its move in gh-9064), at which point the
__getstate__
/__setstate__
pickling wouldn't work correctly any more. Also, however, there was no__getnewargs__
andnew
didn't have a zero-argument form, so this wouldn't have worked either.Details and comments
No changelog because this is a private class, and it doesn't actually seem to be causing us problems.
