Lux
The Lux Programming Language
...Read carefully before using this project, as the license disallows commercial use, and has other conditions which may be undesirable for some. The language is mostly inspired by the following 3 languages. Clojure (syntax, overall look & feel), Haskell (functional programming), and Standard ML (module system). They are implemented as plain-old data-structures whose expressions get eval'ed by the compiler and integrated into the type-checker. The main difference between Lux & Standard ML is that Standard ML separates interfaces/signatures and implementations/structures.
