This makes the code easier to understand and navigate, and also detected a few of bugs: 1. Missing brackets on e.upper. (Fixed) 2. Not strictly related to types, but a lot of the regexes were not raw strings and therefore contained invalid escape sequences. Python prints a warning about these in recent versions. (Fixed) 3. Expression in `process_pseudo_instructions()` that is always false. (Not fixed) 4. Missing definition of `log_and_exit()`. (Fixed) This is validated via pre-commit in CI.
