print(ee.List([])); // []
print(ee.List([null])); // [null]
print(ee.List([true])); // [true]
print(ee.List([1])); // [1]
print(ee.List([ee.Number(1)])); // [1]
print(ee.List(['a'])); // ["a"]
print(ee.List([[]])); // [[]]
print(ee.List([ee.List([])])); // [[]]
print(ee.List([[], [[]], [1, [], 'a']])); // [[],[[]],[1,[],"a"]]
