Right. I think a key miss was underestimating value of code that would work w both 2 and 3. This avoids need to upgrade all at once. Relax things a tiny bit in 3, back port to 2 via futures, get a library like six going. It could have been a ton easier. In fairness by 3.5 maybe they’d realized this, but a lot of lecturing was done before. Initially recommendation was to upgrade all dependencies and programs to 3 and not try and make dependencies work w both
