An easy to use, fast extensible effects library with seamless integration with the existing Haskell ecosystem.

Direct-Style Programming for ZIO

Functional, composable, asynchronous, type-safe Python.

A direct-style effect system in Scala 3 that tracks effects using context parameters

A small, elegant, general-purpose functional language. Effects are in the type signature, including ones you name yourself. The compiler is self-hosted and the only one there is. Two peer backends, JVM bytecode and C, plus a cuTile device backend for Dawn kernels on NVIDIA GPUs; the same answer on every road is held by a gate, not a promise.
