Utilities for formatting Strings.

Example

fn test_to_string(val) {
  fmt.to_string(val)  // Converts any value to String
}

fn test_append(a_list) {
  case a_list {
    [] -> "list is empty"
    [x] -> "list has one element: " |> fmt.append(x)  // Appends any value as a String
    [x, y] -> "list has two elements: "
      |> fmt.append(x)
      |> fmt.append(" and ")
      |> fmt.append(y)
    _ -> "list has more than two elements"
  }
