Names being self-explanatory is certainly a worthwhile goal, even though I guess that it's a bit more on the idealized side of things. Functions will often not be fully self-explanatory, which is likely just a matter of reality. I mostly just don't want us to end on the other side of the spectrum where we go militant on "Every function must be no longer than 2 lines of code such that it can be self-explanatory". And yes, I'm of course stretching what you are saying quite a bit, I know that this is not what you want to say. I'm merely writing down my own thoughts while thinking it through. So, that being said, I agree that we shouldn't use arbitrary suffixes, as these are quite hard to understand indeed and typically don't really provide any context. So as long as we interpret this rule leniently I'm happy with it. Patrick
