Typescript-Like Notational Shortcuts

On the theme of the addition of pip operators to indicate union, I was wondering what people think of using the following shortcuts for type hints. * type[] be a short-hand for List[type] * [type1, type2, type3] be a shorthand for Tuple[type1, type2, type3] * similar ideas for dictionaries and callables with (perhaps with javascript-like arrow notations?) I just think something like this would be easier to read. For example, a lot of functions that return tuples generally are immediately unpacked when it's used, so I think this is a more clear and concise way of stating that this is that it returns three elements: an element of type1, an element of type2 and an element of type3. In other words, the fact that it's a tuple does not matter much.

I talked about this before but I have slightly different suggestions list[type] becomes [type] tuple[type1, type2, type3] becomes (type1, type2, type3) dict[type1, type2] becomes {type1: type2} set[type] becomes {type} Callable[[type1], type2] becomes (type1) -> type2 class MyTypedDict(TypedDict): name: str age: NotRequired[int] becomes {name: str, age: NotRequired[int]} Unfortunately, the steering committee rejected the callable syntax last year even though I think the proposal was elegant and a lot of efforts went into it. Maybe they will reconsider it in the future with some modifications? I don’t know. Abdulla Sent from my iPhone
