summary

An experimental Scala compiler optimized solely for compilation speed claims dramatic wins: a prototype type checker handles an 11k‑line nontrivial corpus in 33 ms for 11k LOC, reports ~300k lines/sec, and measures 20x faster than scalac for hot runs; JVM bytecode generation and full Scala features are out of scope, the compiler implements an eager scheduling/scoping/outline pipeline to avoid lazy global completers, and early results show real parallelizable gains without full language support.
