If you haven't read Landin's "The Next 700 Programming Languages", you should. I don't know if it's still outside the ACM paywall, but you'll find it in a web search if not. It introduced the offside rule -- not actually what Python has -- inspired by mathematical notation. Note "it can be mixed freely with [...] punctuation" (e.g. Haskell). The paper talks about "physical representations", relevant to syntax highlighting mentioned below (or "fontification" in Emacs, reminiscent of typefaces in the publication language of ALGOL).
