I am pretty skeptical about the whole idea about adding such exceptions to the single mutable reference rule. It may be safe to share references to simple structs in terms of raw bytes access, but as long as some non-trivial invariants ar

It would be nice to know how fast it is in comparison to a similar voxel engine written in a language like C++ or Rust.

Having latin alphabet with diacritics and digraphs is still better than something like Arabic. Some non-latin alphabet with letters separate from each other (like Greek, Cyrillic, Armenian, Georgian, etc.) would be fine too.

It's objectively so horrible. Letters have similar form to each other, joints between them makes it harder to take them apart. As I understand, Arabic alphabet wasn't designed to be practical for daily use and only for writing sac

Why do people still use this horrible-looking and hard to process alphabet? Why not switching to latin (as some countries did) or at least to reform it so that it's easier to type and to read?

It's unlikely. It means rewriting all these Electron apps using something more performant, which is pretty costly.

Any change in basic arithmetic should be backwards-compatible. The easiest way to eliminate UB is to define signed overflow for existing types as 2-complement. But new types with different semantics (or maybe library wrappers) can be create
