Long-simmering side project that is finally ready to see the light. HAMTs are a cool persistent data structure and implementing one has been a lot of fun. Beyond the code, there is likely some value in the extensive and largely complete implementation docs; basic benchmarks are linked in the README, too. Kind of aiming to be "the libavl for HAMTs". That is obviously a high and aspirational bar but a distinct possibility if it stirs up a little interest and/or contribution. Anyways, it's time for this to go out, collect feedback and maybe even some use outside of toy projects. Let me…

LoopMix128 is a fast C PRNG I wrote for non-cryptographic tasks. GitHub (MIT): https://github.com/danielcota/LoopMix128 Highlights: * ~0.37 ns/value (GCC 11.4, -O3 -march=native), 98% faster than xoroshiro128++ and PCG64. * Passes TestU01 BigCrush & PractRand (32TB). * Guaranteed 2^128 period. * Proven injective (192-bit state) via Z3 SMT solver; allows parallel streams. * Core requires only stdint.h. Seeking feedback on design, use cases, or further testing.
