False positives for TypedDicts

[alicederyn]

The following code:

class ExampleTypedDict(typing.TypedDict):
  field1: int
  field2: str

Results in unused variable 'field1' (60% confidence) (same for field2).

As this is how TypedDicts are designed to work, probably the correct solution is to special-case them.

For clarity: typed dicts are used this way:

instance = ExampleTypedDict(field1=1, field2="hello")
assert instance["field1"] == 1
assert instance["field2"] == "hello"
