We'll learn more news from Apple leading up to its March 4 event.
there’s still work to do. the biggest gaps are SIMD prefilters for non-literal patterns - the dotnet version gets a lot of mileage from vectorized character class membership tests that we don’t have yet - and the bidirectional SIMD routines needed for our right-to-left scanning. pattern-specific optimizations like start-set inference and alternation simplification are also on the list. there’s also a lot of other low-hanging fruit - we don’t have any statistical optimizations yet, the Unicode classes could be baked in instead of constructing them while parsing, the memory usage could also be improved, there are many pattern-specific shortcuts we could add, and so on. but i hope the benchmarks show that it’s already competitive and useful in its current state.

“Adopting two-for-one deficit reduction would send a signal to creditors that our government is serious about controlling the growth of debt, even as we engage in near-term borrowing to support the economy,” the report said.
