(+ 1 2) ; Add two numbers.
Would become (comment (+ 1 2) "Add two numbers")
With semantics like const. (+ ; Adding
1 ; one
2 ; and two.
)
To ((comment + "add")
(comment 1 "one")
(comment 2 "two"))
You could display comments as popups, marginalia, or even in a traditional fashion (since some intent is captured by the comment scoping. You could also have different types of comments like annotation to have different kinds of display types.
I think there's an argument that pixel art was designed for CRT displays and thus optimized for it. I think of it like Pointillism: the work is made of little dots, but the point is for you to see the entire work blend together. And for low resolution works like retro games, they often hold up well on CRT (especially real ones). However, I think modern games with the pixel art aesthetic look best crisp.
To each their own tastes, though.
