We concluded that (1) No. that was co-developed with it. As I am unable to tell if this problem stems from my pypy3 installation or from something else I am describing here all the steps that I have followed so far: don’t really have an obvious corresponding type (e.g. will never be monkey-patched” – same with len() or list(), © 2020 Canonical Ltd.
