    let b = identity:[string]("hello")
    let c = identity:[f64](3.14)
    return 0
}

Multiple Type Parameters

fn pair:[T, U](a: T, b: U): (T, U)
{
    return (a, b)
}

Generics with Numeric Promotion

fn add:[T](a: T, b: T): T
{
    return a + b
}

fn main(): i32
{
    print(add:[i32](1, 2))      // 3
