Is it a coincidence that all these quality life things start to pop up after C++ is facing real competition for the first time? Seems a bit odd to add print after using std::out for 30 years.

I've had great success with autovectorization in Rust. Majority of non-branching loops seem to consistently generate great assembly.

  fn validate_ascii(bytes: &[u8]) -> bool{
      bytes.iter().fold(true, |acc, b| acc & (\*b <= 127))
  }

This check will likely be the best for english text/code. You can check in varying size chunks depending on how common you think non-ascii will be. If its ascii you can move 128 bytes forward on avx2 in a couple of cycles.

If you prefer reading Python, I implemented the decompressor not too long ago: https://github.com/LaihoE/tiralabra

I've been wondering what is the "new" innovation about concurrency is in Go? Since most languages provide some type of channel/lightweight thread, what is the hype all about? I don't think Go makes the "hard" stuff in concurrency any easier, mainly the easy stuff becomes very easy, but in concurency most your time is spent in the "hard" parts.

Couldn't agree more about the rust API. Python API seems OK. Found it very complicated to use and just clunky in general.

I find it inconstant to be so pedantic about unused vars/imports to avoid bugs, but then leave error handling to what it is.

I really want to love this language, a fast and simple garbage collected lang, but feel like they missed the spot a little. I just wish they did something different with error handling / nil, doesn't feel right for the language. Also whats up with stuff like unused imports being such a big deal?
