Tuples especially, and more specifically how the language supports their unwrapping. for idx, entry in enumerate(list) vs. list iterators in Java where you have to repeat complex types at least 3 times and get about 5-10 times more code when it would only have to be about 2 times to achieve static type safety. Lack of typedef and the resulting drive towards dummy classes is exacerbating this problem further.
