switch expression about zig

[andrewrk]

How about (note the else):

struct Point {
    x: u64,
    y: u64,
}

enum Foo {
    One: i32,
    Two: Point,
    Three: void,
}

fn f(foo: Foo) -> void {
    switch (foo) {
        One(x) {

        },
        Two(*point) {
            // same as the `*` in the for loop. now point is a pointer to the struct value
        },
        Three {

        },
    } else {
        // `default` in C
        // `_ =>` in rust
    }
}
