chumsky moment

wow, I have to say, tail recursion, slices, iterator transformers and shadowing are great building blocks for parsers. I'm actually way faster at defining and modifying procedural parsers with Rust's tools than I am with Chumsky. I actually understand which of my checks are greedy and lazy now!

I swear to god, getting Chumsky to do my bidding has almost taken longer than writing a parser by hand. I'm not looking for operator precedence, I'm not looking for complicated rules or anything, the main part of my language is literally just S-expressions, with some top level bells and whistles.

I don't even have a working lexer yet because I wanted to use this piece of shit library which usually matches the fewest possible characters to parse significant newlines but the Padded combinator takes as much whitespace at the end as it can find, and a host of other atomics don't actually adhere to the library's lazy principle in their procedural implementation. I've had enough. I'm going to bed, and tomorrow I'm writing tickets.

Actually, I'll probably also write PRs because I actually want the fixes to exist and not just complain about the problems, but I also really want to complain before I get started on that because I spent about two weeks just on this bullshit.
