The Display impl for Simple shows raw output and expectations, which is awkward for whitespace, such as '\n':

Example:

use chumsky::primitive::{end, just};
use chumsky::Parser;

type Error = chumsky::error::Simple<char>;

fn main() {
    match parser().then_ignore(end()).parse("\nblah") {
        Ok(_) => panic!("Should not happen."),
        Err(es) => {
            for e 

Currently we only report an error when the entry credit balance is 0. whatsitlike on the discord suggested that we should provide a warning if funds are running low, perhaps with a config configurable threshold.
