Hello, World!

A first program: a const, a function with an annotated return type, and the pipe operator |> feeding a value into a call.

const test1 = 2

/// Multiplies two integers and returns the result.

fn mul(a: int, b: int) -> int {
  return a * b
}

let result = test1 |> mul(2)
print("Hello from Zolo!")
print("2 * 2 = {result}")
