Faster Scala Collections with Scalaxy/Streams!
summary
Scalaxy/Streams delivers a concrete optimizer: a compiler plugin and macros that rewrite chained collection ops into tight while loops, doing side-effect analysis with trusted-API whitelists and offering safe / aggressive / foolish strategies. Microbenchmarks show common speedups (10×, sometimes 50×) and iterators remain 5–20× slower; jar size falls ~5–7% and example code size drops up to 60%. Implementation uses quasiquotes, symbol/type hacks, reflection to reparent owners and ahead-of-time typing; the plugin already handles most of the Scala library.
