We’re pretty excited about this project, so this is a double notice if you read Thursday’s annoucement. But we’ve officially released our new Open Source project, Freestyle.
Freestyle allows you to build stack-safe purely functional applications and libraries that support parallel and sequential computations where declaration is decoupled from interpretation. Freestyle encourages programs built on top of Free algebras that are interpreted at the edge of your application ensuring effects are localized and performed in a controlled environment. Applications built with Freestyle can be interpreted to any runtime semantics supported by the interpreter target type.
You can read the full release notes here: Freestyle v 0.1.0.
