Arza is a functional programming language with multiple dispatch, immutable data structures and actor model out of the box.

Arza is in a prototype state of development. Current interpreter is implemented in Python (without RPython)

There is no REPL at the moment.

Detailed documentation

To run tests

python targetarza.py test/arza/main.arza

or better use pypy
