A dynamic programming language inspired by Python and E.

Mu

A purely statement-oriented language (like Basic) designed for teaching programming 1-on-1.

Mushroom

An experimental functional programming language with an emphasis on type inference and aesthetic syntax.

Myrddin

A systems language aiming to fit in a similar niche to C, but with fewer bullets in your feet.

Never

A simple syntactically-scoped, strongly-typed, call-by-value, functional language.

Dynamic object language modelled after Smalltalk, with a gradual typing system affording expressiveness rivalling ML or Haskell.

Owen

A language close to C with modern touches.

oXyl

A functional language designed to work on parallel CPU and GPGPU using a functional paradigm and context system to contain side effects.

Plasma

A language that balances functional and imperative programming, and has state-of-the-art concurrency and parallelism features.

Pikelet

A friendly little systems language with first-class types and unboxed data.

PISC

An attempt to make concatenative programming less mind-bendy via locals, closures, and syntactic sugar.
