I totally agree that good compostability and keeping things simple is good. I don't see the relation to the Title's reference (how our working memory can only hold ~7 different items). Those studies are about distinct short term individual items. This has nothing to do with programming abstractions, those aren't kept in our working memory (not like they seem to be describing). It's not like we can only remember 7 different methods at once.
