s2prot VS hylo

SC2 replays are MPQ files, which is a proprietary format created and used by Blizzard. It's an archive that may contain multiple files stored with different compression and optionally encrypted. I wrote a lib to parse MPQ files that embodies SC2Replays: https://github.com/icza/mpq. I also wrote an SC2 replay parser that is more or less a port of the official s2protocol: https://github.com/icza/s2prot

vm = virtual machine/memory?

I'm porting this Python library to Rust: https://github.com/Blizzard/s2protocol.

For the shitty, first pass prototype code I've written so far I've seen a ~30-40x speedup compared to the Python implementation and a ~2x speedup compared to a Go implementation by someone else: https://github.com/icza/s2prot.

That is why I chose Rust over a GC language like Go. It's a lot faster out of the box, even without me having a strong understanding of memory operations.

Or Val[0], now called Hylo (for a good reason), or V[1].

The evolution of C++ has been a multi-decade history of dealing with difficult reality.

I have great hope that Herb can create with his cppfront project “The Very Best of C++” to carry that tremendous legacy forward.

If I was to throw my hat into a “C++ successor”, it would be https://www.hylo-lang.org/ with its “all the safeties” and “tell you when you’re doing it sub-optimal” approach.

> Hylo is a language for high-level systems programming that promises safety without loss of efficiency. It is based on mutable value semantics, a discipline that emphasizes the independence of values to support local reasoning. The result—in contrast with approaches based on sophisticated aliasing restrictions—is an efficient, expressive language with a simple type system and no need for lifetime annotations.

> Safety guarantees in Hylo programs are verified by an abstract interpreter processing an intermediate representation, Hylo IR, that models lifetime properties with ghost instructions. Further, lifetime constraints are used to eliminate unnecessary memory allocations predictably.

A model without lifetimes is also being explored in other languages, e.g. in Hylo. It sacrifices expressiveness, but on the other hand you don't have to deal with explicit lifetimes!

Why go through all the trouble when you can do this: https://www.hylo-lang.org/ and not spend a second thinking of lifetimes? No, copies will not be issued unless necessary.

Or why not keep exploring this idea as well? More research-oriented than the first one right now, though, so take it with a grain of salt: https://vale.dev/

Get rid of references at the cost of some expressivity (see Hylo, formerly Val)
