Missing import in example at dataclasses.rst #91673
Description
Documentation
Found that the typing List is used in example, but import is missed at dataclasses.rst file.
In this example:
@dataclass
class D:
x: List = []
def add(self, element):
self.x += element
the import from typing import List is missing

I'm not sure how important this is. The example already says the code isn't valid. Maybe just use "list" instead of "List".

Sure @ericvsmith, but the example in the documentation doesn't run.
Your suggestion for using list instead of list works, as long it is defined as
x: list = field(default_factory=list).However, I think the example is about forcing the datatype in the list using List from typing.
This works (as example only):
this doesn't work
