lang/gleam 1.9.1 DragonFly

Gleam is a fast, friendly, and functional language for building type-safe, scalable systems.

The Gleam compiler itself is written in rust.

Gleam uses the BEAM runtime, and using the same actor-based multi-core concurrency, with zero runtime overhead and full inter-operability with Erlang, Elixir, and LFE.

It has all the features you'd expect from an ML derived language, including algebraic data-types, immutable data structures, full type inference, fast compilation, generics, no nulls nor exceptions, and a few bonus features such as helpful error messages.
