I didn't notice the point at which this turned into a discussion about RAII or whatever a GC is in 1990's books' definitions. And why would an arena not be manual memory management if I make explicit allocations that make explicit use of such arena, and I free the arena on a suitable occasion? I'm even likely to write the arena myself, but not necessarily. I have this simple and (in my mind) very useful equation of manual memory management ~ writing code to manage memory. Conversely, GC ~ using an external runtime (such as that in JRE) that helps you to avoid writing any memory management code at the cost of giving up control. Ok, let's lose a sentence about ARC, I don't care if you name it GC or not, and I don't use it. I'm not interested in other pointless taxonomic discussions. Whatever, man.
