I disagree. Callback based programming forces you to modularize around asychronous/IO calls instead of semantic cohesion. Naming functions doesn't solve that problem. On the contrary, you get seperate lexical units that are not separately reusable and make no sense on their own. They are simply fragments of code that's supposed to be executed before or after some IO operation inside another function.
