The way to code in hell would be vi (not vim) but without any command support >:D Starts in insert mode, and that's it. Kind-of like the old days where computers had no persistence and you just had to type in all of your code at once.
I finally got it the stage where I wrote an editor - and I've been using it.
Not a good editor. Append only, has to be typed directly into the machine. Does that classify?
