Eta lang - Haskell On JVM
summary
Eta compiles GHC’s STG intermediate form to JVM bytecode and runs Haskell on the JVM; core libraries with C FFI are patched to Java and the build tool mirrors Cabal. Tail-call optimization turns recursion into loops so 10 million tail-recursive calls can complete, and benchmarks show a naive quicksort is ~2x slower while an optimized sort runs at ~60% of Java speed. Interop supports calling Java, exporting functions, a servlet wrapper for Haskell handlers, and a Game of Life demo with Haskell logic driving JavaFX. Version 0.8, active community, still maturing.
