I'm not sure if you misread my comment, but my point was that it's far too easy to accidentally introduce bugs in merge commits that go unnoticed for a long time.

I've never seen a rebase gone awry introduce production bugs, but I've known multiple gnarly bugs caused by errant merges. YMMV.

First time I've seen aliases using other chars other than a-z; care to share your dotfiles?

It's a neat trick to explode your alias namespace, since you'll never see a tool published named `ls-` So you have reserved a huge "address block" for your personal aliases :)
