let expression = hcl::expression!({
    foo       = true
    "baz qux" = [1, 2]
    (other)   = "world"
});

let expected = Expression::Object({
    let mut object = Object::new();
    object.insert(ObjectKey::identifier("foo"), true.into());
    object.insert(ObjectKey::string("baz qux"), vec![1u64, 2].into());
    object.insert(ObjectKey::string("hello"), "world".into());
    object
});

assert_eq!(expression, expected);
