```mist
// Generic function
T id<T>(T x)
{
    x
}

// Generic struct
struct Pair<A, B> {
    A first,
    B second,
}

// Generic enum
enum Result<T, E> {
    Ok(T),
    Err(E),
}

// Generic with trait bounds
T max<T : Ord>(T a, T b)
{
    if a > b { a } else { b }
}

// Lifetime generics
void process<'a>(&'a str& data)
{
    // ...
}
```

Generic syntax uses `<` `>` delimiters. Lifetimes are prefixed with `'`.
