in plain english

Gleam is a statically typed programming language designed for building type-safe, scalable systems. Based on the description and topics, it compiles to run on the Erlang virtual machine, a runtime known for handling many concurrent operations reliably, and emphasizes friendliness and type safety, meaning the compiler catches type errors before the program runs rather than at runtime. The compiler itself is written in Rust. The README does not provide further detail about its features, architecture, supported platforms, or use cases, so a complete explanation is not possible from the provided data alone.
