Case expressions: refactor examples involving random input to permit easy variation of results

[3willows]

Hi!

I am totally new to the language, just started playing with the playground after hearing about Gleam from a Red Badger meet-up.

As I was mucking around, I made light changes to the examples involving random inputs as follows (e.g. this), which allows me to see different cases being triggered in the output.

import gleam/int
import gleam/io

pub fn main() {
  example()
  example()
  example()
}

fn example() {
  let x = int.random(5)
  io.debug(x)

  let result = case x {
    // Match specific values
    0 -> "Zero"
    1 -> "One"

    // Match any other value
    _ -> "Other"
  }
  io.debug(result)
}

Just wonder whether this is an ever slightly easier example for absolute beginners to work through.

Hello! Sounds like a nice idea to me. Or perhaps randomness could be abandoned and a few different values could be passed in.

Great to hear the Badgers are chatting about Gleam. I've a lot of time for Stu and the gang, they're a great bunch.
