It was pretty bad that easy_install came out with no easy_uninstall. Plus some packages are in your system's package manager (which I think is great because I'm sick of every language having its own package manager when my system's (Gentoo) is better) and some aren't, or the latest versions aren't. Plus there's the virtualenv stuff, or the general problem of your dev environment not matching the deploy environment. Needing to have both Python2 and Python3 on your system in some cases. Some packages have C/C++ code so you need a compiler, and all the dependencies that implies. On Windows I think Python development is a joke, last time I did anything extensive there I think I ended up installing Enthought's distribution and picked off from http://www.lfd.uci.edu/~gohlke/pythonlibs/ as needed. I don't see how the Go situation on Windows could be worse than that.

I'm not a huge stickler for non-local consistency -- one of the things I like about Nim is its apathy about naming conventions (foobar is the same symbol as foo_bar or fooBar, func(arg) is the same as arg.func()...) -- so that's probably why I don't find the consistency factor a huge issue. When a language and its ecosystem has it, it's nice, but when it doesn't, it's not really a thing that annoys me.
