Would people say that (), ', and # are the main default privileged symbols in Racket?

I’m not sure I would call them that. The full set of built-in delimiter characters also includes [, ], {, }, ", ,, ;, and backtick, which slack formatting does not allow me to easily include in a message. All of those are equally special according to the default readtable.

ahh I see thankss

I was definitely missing those

\| and \ are also special characters when used for escaping symbols, and . is special when used for pair notation or infix syntax.
