I do like the the option of using unicode symbols in Julia, but this need not be thought of as only a language feature. Emacs allows you to substitute any text for any other when viewing a document, so you can pretty much do the same in Emacs for any language. I did this when editing LaTeX papers full of logic symbols, which Emacs would display as the symbols themselves rather than as the underlying LaTeX markup. It could do the same for Lisp or any other language.

> Emacs allows you to substitute any text for any other when viewing a document Do you have a reference or search term for that? My Google-fu is failing me.

Vim can do this to (with a plugin). And you can enter Unicode in the Julia REPL by entering the TeX command and hitting TAB.
