Here's another crazy idea: don't run 'git checkout ...' on a dirty work tree. Problem solved.

Another one: don't reuse filenames as branch-names.

To be honest: I have the same problem with careless invocations of 'rm' ruining my day but when I'm muttering curses it is at my lazyness/stupidity and not at bash completions or the behavior of 'rm'

Honestly, it's annoying that we all use single-version filesystems. It was a good idea back when computer storage consisted of a big rotating metal drum and a major government could only afford 1MB of storage.

Now that 1TB is like $70, we should just keep every filesystem state around. Maybe not forever, but so that "rm -rf *" is just a "gah, that's not what i wanted!" moment instead of a "the rest of my day is ruined" moment.

Premature optimization is the root of all data loss.
