Blazing Fast Zig Parser: 2.75x Speedup

A developer has created a high-throughput tokenizer and parser for the Zig programming language that's 2.75x faster and uses 2.47x less memory than the mainline implementation. The project leverages SIMD and SWAR techniques, along with clever bit manipulation and perfect hash functions, to achieve significant performance gains. Further optimizations are planned, with the ultimate goal of integrating this parser into the Zig compiler itself.
