You may want to investigate Frege. Quoting from that page:
“Frege is a non-strict, pure functional programming language in the spirit of Haskell.”
“Frege programs are compiled to Java and run in a JVM.”
Based on a brief perusal of the language specification, Frege looks to be nearly a Haskell clone. Perhaps the phrase “in the spirit of Haskell” is simpy intended to set the proper expectation.
