Some of that is so angry! :-) I understand though. Being a big mercurial fan myself, I tried the same approach when forced to use git at work. It was good for learning git, but after a while I just switched to hg-git and I am much more at peace. Ran into a little snag yesterday when a co-worker wanted to pull on of my local (hg) commits into his git repo. Not sure if there's a way to do that.
Wouldn't this be considered an anti-pattern? Similar to switching to emacs just to make it work exactly like vim? Just use vim, or in this case, just use mercurial?
There's spacemacs and evil. I don't see a problem.
