Beauty and the beast Haskell on JVM
summary
Eta targets GHC compatibility by compiling STG to JVM bytecode and claims you can reuse hackage packages with Cabal patches for C imports; benchmarks show naive quicksort about twice as slow and a tuned real quicksort roughly 60–70% of Java speed, while a 12‑queens microbenchmark improves after fixes. Practical work includes a pong and Game of Life backend that runs on Tomcat/servlets, but current 0.7x tooling has edge bugs (one tail‑call fix was required), limited automation for Java imports, and a very small community.
