Hilariously it was a copy/paste situation that I went "oh, that's kinda neat, I'll leave that" so I'm glad you noticed. (I am often guilty of nesting thoughts (inside of other thoughts) which is kind of amusing (even though I've never found lisps particularly easy to read)).

I think typical writing style guides suggest the single-quote for nested quotes.

"I think he said, 'No way?! Zig for the win!'"
