Excellent point! So far I get the impression that 'level of abstraction' and it's benefits/downsides can be separated into a bunch different categories (readability, conciseness/concision, ease of getting back into things after being away, protection from various classes of errors, etc.). Ease of debugging will now be another one on my list.
