Someone created a bestiary of “List Code Typography”:http://kazimirmajorinc.blogspot.com/2012/03/few-examples-of-lisp-code-typography.html and my immediate gut reaction upon seeing the earliest possible examples was that the only thing that could ever have been more confusing than all the parenthesis in the world was if you had to put commas in-between every goddamned thing.
The language I’m currently learning, Haskell, has its roots in the Lambda Calculus as well, but goes entirely in the other direction–no punctuation at all.
