When typing Python code, the special `*args` and `**kwargs` params are typed based on their contents, e.g.
```python
def foo(thing: int, *args: str):
...
def bar(thing: int, *args: str, **kwargs: Union[int, float]):
...
bar(-3, "G", spam=80, eggs=4.4)
foo(44, "abc", "xyz")```
And in this case, the types are passed to a different func (`Query.__init__`) which has specific arguments, so it is best to not give **kwargs a type, or, better, copy the parameters of that function (but I haven't done this here).
This also applies to `Transaction`.
PS I know this is a stupidly minor change but it annoys me, having to write `noinspection PyTypeChecker` before every datastore query.

@crwilcox I'm -1 on this change myself, but will leave it to you to decide: if we are going to change how we document |

I spent some time researching. This is also how mypy interprets types. I agree though @tseaver, we likely need to do this more broadly. |
