Oh, so you weren't around when Requests went 2.0 backward-incompatible (because they changed .json() with .json, or the other way around, can't remember) and half of PyPI, with its happy-go-lucky ">=1.0", broke...?

Since then, most people have learnt that you pin first and ask questions later.

Indeed. I just hate the versions hell (as well as dealing with old versions of a language although I happen to love old hardware) so much that I've been ignoring the whole Python until the 3.6 release waiting for the time when one will be able to use all the Python stuff without bothering to learn anything about Python 2.x. It took 10 years of waiting but we are finally here now and now I enjoy Python :-)

I just encountered the fun fact that Pip 18.1 broke Pipenv whereas Pip 18.0 worked just fine.
