hac VS aoc-2020

HAC's "Semantics" target now sets up identifier lists, a feature that happens to match the need for a smart editor's auto-complete feature. In particular, the LEA team seems to be happy about that new development.

HAC: release 0.2 with an interface between a program being run by HAC and the program running HAC as an embedded compiler. If you feel confused by reading that, it is normal ;-). Perhaps the following blog post will help clarifying things... https://gautiersblog.blogspot.com/2022/06/hac-as-embedded-compiler.html List of HAC releases here: https://github.com/zertovitch/hac/commits/master

Web site: http://hacadacompiler.sf.net/ From there, links to sources, and an executable for Windows.

HAC: release 0.1 with support for packages; improvement of the VM with instructions that do the job of two or more instructions. List of changes here: https://github.com/zertovitch/hac/commits/master

I've tried it a few times and solutions were surprisingly elegant! E.g., 2020-01-p2.

Figured I'd post my benches as well, see below. Everything done in Rust (link to source).

Here's my day 24 in Rust, using SIMD as usual :) (and offset coordinate encoding to make a SIMD-friendly 2-D cell grid)

Borrowed both ideas in my version :) On my input your version runs at 3ms, mine in 1.5ms, so it might be faster on some inputs (link). I initially started with something similar to yours but then figured why not use 512-bit ints, so that the notion of 'head' and 'tail' disappears as your head then stays at position 0 (so, e.g., to remove a card, you just right-shift the whole bigint). Also used a tiny bit of simd along the way.
