Almost 90% line coverage, 95%+ function coverage. 2346 E2E tests + a few dozen unit tests. There's a lot of low hanging fruit that could push this close to 98% across the board.

![Screenshot of an implementation of a Box[T] struct in my language
```
struct Box[T] {
pub var value: T;
}
impl Box[T] {
pub fun new(value: T): Self[T] = Self {
value: value
};
pub fun get(self): T = self.value;
pub fun map[U](self, map: fun (T) => U): Self[U] = Self.new(map(self.value));
}
let box_a = Box.new(5);
let box_b = box_a.map(fun (value: f64): f64 { value * 2 });
print box_a.get(); // 5
print box_b.get(); // 10
