Pretty sure they're not possible in the sense I mean, for the same reason as above - you need custom moves for this. I'm referring to a pointer (not an offset; a pointer) that automatically adjusts itself when copied or moved. So that it always points somewhere N blocks before/after itself. These are just two examples, to get the point across that Rust actually lacks some capabilities (since somehow that surprises people). You can find more.
