gleam-lang/gleam ? reverse-engineered prompt

Build me a friendly programming language called Gleam that helps people write type safe software for scalable systems.

I want the project to include the compiler, a command line tool, formatting support, and a language server so it feels good to use in an editor. It should be able to compile code for the Erlang ecosystem and have a clean developer experience with good errors, tests, and clear docs. Please make it feel polished, with a simple workflow for creating projects, checking code, formatting files, and running builds.

If you need to look up current docs online while filling in any gaps, go ahead. Focus on making the language and tools feel approachable, reliable, and ready for real use.
