std::list::len(list) -> int
std::list::get(list, int idx) -> any | null
std::list::set(list, int idx, any val)
std::list::push(list, any val)
std::list::pop(list) -> any | null
std::list::remove(list, int idx) -> any | null
std::list::add_in_place(list, int idx, int delta): adds to an int element in place

use pie/std;

def void main() {
    let list xs = std::list::new();

    std::list::push(xs, 2);
    std::print(std::list::len(xs));
