The code in the screenshot/asciinema isn't s-expr by any common conception of the term, or as a Lisp would parse it.
That argument to flatten is in fact [macroexpanding manually, forgive errors]
which flattens to
---Parsing sexprs is quite easy, no need to use a complex parser generator. The core of parsing sexprs is you have a "read_list" function, which accumulates values until it finds a ')', and whenever you encounter a '(' character, you recurse into that same read_list function. You don't even need a lexer. Also, this is divided in 8 crates for some reason... don't take this the wrong way, but is it the result of vibe coding? | ||

Doesn’t seem vibe coded to me. The crates aren’t unreasonable: data structures, parser, formatter, repl, “util,” some proc macros (which have to be in a separate crate in rust), and a VM. |
