What I've been working on recently: an effect-oriented homemade language that compiles to WASM / JS / C. I'm in the middle of adding a package manager and adding more language features. https://github.com/emela-lang/emela https://docs.emela.dev Looks like:
emel
import Std.Console.{Console}
import Std.Platform.{Platform}

error Negative(n: Int)

fn half(n: Int) -> Int fails Negative {
  if n < 0 { fail Negative(n:) }
  n / 2
}

fn main() {
  with Platform {
    console = use Console
    [10, -4, 7]
      |> List.map(fn(n) { Int.to_string(half(n)) escape { Negative(n:) -> "#{n} is negative" } })
      |> String.join(", ")
      |> console.print_line
  }
}
sh
$ emela run main.emel
5, -4 is negative, 3
