Lua Fun is a high-performance functional programming library designed for LuaJIT
tracing just-in-time compiler.

The library provides a set of more than 50 programming primitives typically
found in languages like Standard ML, Haskell, Erlang, JavaScript, Python and
even Lisp. High-order functions such as map(), filter(), reduce(), zip() will
help you to write simple and efficient functional code.
