Динамический язык на рантайме Haskell, с паттерн-матчингом, континуациями, обьектами, блекджеком и шлюхами:

atomo is a small, simple, insanely flexible and expressive programming language. its design is inspired by Scheme (small, simple core), Slate (multiple dispatch, keywords), Ruby (very DSL-friendly), and Erlang (message-passing concurrency). it is written in and piggybacks on the Haskell runtime, permitting access to all of its power (and libraries!) through a thin layer.
