23: Gleam and Static Types with Louis Pilfold

We talk with Louis Pilfold about how he created Gleam, a static typed language that runs on the BEAM. Louis explains some of the challenges with bringing static types to the BEAM and shares ideas on what can possibly be done about it. We learn how Gleam got started, how it works, and how Elixir and Erlang can interop with it. We cover the recently released Gleam OTP work, talk about Type Driven Development and much more!
