Every now and then people share languages with very minimal or very uniform syntax (think Lisp, or Haskell, or Forth) and go "look, all the noise is gone". And to each their own, and familiarity goes a long way, but I think I've pinned down my feelings about it, which is "that wasn't noise, that was signal; I was using as scaffolding when reading the code and now I have to wade through every token linearly".
@jrose I've been thinking about this, or something related, in the context of SQL—a language that largely favors keywords over punctuation—which I habitually write in the classic SELECT foo FROM bar WHERE baz style, and which some of my colleagues write in all lowercase.
The difference, I think, is syntax highlighting, which they all learned with and take for granted. The uppercase keywords originally made up for the lack of that.
