The day that commands in the rm family start exposing that kind of behaviour, where not only they offer suggestions a la Google ("twst.htm doesn't exist - did you mean to rm test.htm instead?") but also assume that that's what I meant ("twst.htm doesn't exist, so I went out of my way for you and rm'ed test.html instead, which, hey, you only worked on for 8 hours straight and haven't backed up yet. You're welcome, bro.") I swear I'm never touching a computer again.
