It's kind of a bummer that "skins/themes" never caught on for programming languages. You see it once in awhile, I think some compiler people at one of the FAANGs did an OCaml skin/theme/alternative syntax (reason? something). And there's stuff like Elixir that's kind of a new language but also an interface to an existing world (very cool, Valim is a brilliant guy).

But you could do it for almost anything. I would love the ability to hit a key chord in `emacs` and see things in an Algol-family presentation, or an ML family, or a Lisp.

Seems like the kind of thing that might catch on someday. Certainly the math notation in things like Haskell and TLA were a bit of a barrier to entry at one time. Very solvable problem if people care a lot.
