I sort of wonder why I see so much users complaining about package management in Python, meanwhile I'm having a fantastic journey since 2008 with it, with over 50 published open source packages. "Sort of" because I'm suspecting that the users in question just do not want to integrate upstream changes continuously, so, they expect the package manager to help them procrastinating on dependency updates, which has proven to lead to disasters such as npm install, and I'm kind of worried that this is the direction they have been taking. But I admit I use setupmeta for auto definition of the version, and it just makes setup.py even better, but that's basically the only thing I like to add to setup.py, because it simplifies package publishing scripts. I haven't found any feature in pip to verify the gpg signatures that it allows us to upload packages with (python setup.py sdist upload --sign). As for pattern matching is not specific to Python, it's available in many other languages and is a joy to use in OCaml, I see no reason why Python would not have pattern matching.
