* There are a few needless borrows that don't seem to be needed. I even did a quick assembly comparison and posted a q to stackoveflow on it. See [here](https://stackoverflow.com/questions/74910196/advantages-of-pass-by-ref-val-with-impl-intoiteratoritem-impl-asrefstr) * removed several `let _ = ...` when they don't look necessary (even a few ones that were not suggested by clippy (?)) * there were a few `then(|| ctor{})` that clippy suggested to replace with `then_some(ctor{})` -- seems reasonable? * some unneeded assignment+return - keep the code a bit leaner * a few `writeln!` instead of `write!`, or even consolidate write! * a nice optimization to use `ch.is_ascii_digit` instead of `ch.is_digit(10)`
