Muscle memory is weird.

... => roglkpl!("{:?}", args), // rustc: cannot find macro `roglkpl` in this scope

roglkpl is what you get if you try to type println when someone changes your keymap from dvorak to qwerty without you realising. Since starting to teach my hands to type in qwerty about two weeks ago, I occasionally find myself lapsing back into my old way of typing, and sometimes get a few words in before realising that what I’m typing makes no sense. It still requires constant conscious effort to type in qwerty, and a brief lapse in concentration can lead to…roglkpl.
