Hmm. Could you do this kind of code for a static allocation at compile-time too?

I believe https://github.com/rust-lang/const-eval/issues/20 is the entry point into this kind of thing. As you can see, there's a lot of discussion. If it ever lands it'll be farther out.

I don’t think so - you can only use static functions to declare static variables. But you could do it with a macro. It’s debatable whether that would be readable and predictable, though.
