Gleam seems like such a nice language. The language server integrated in its single-binary toolchain looks nice.

The only unexpected thing I've found is the lack of structs/objects. Instead you only have "enums", which they call custom types, and a "struct" is implemented as an enum with one variant, seen in the article:

    pub type Pokemon {
      Pokemon(pokedex_number: Int, name: String)
    }

I mean sure, why not, except you have to repeat the name ("Pokemon").
