I want to write a function `is_bare_dict` to return True for `Dict` and false for any typed dict such as `Dict[int, str]`.

One way I could come up with is something like this:

```py
from typing import Dict, KT, VT

def is_bare_dict(typ) -> bool:
    ktype = typ.__args__[0]
    vtype = typ.__args__[1]
    return ktype is KT and vtype is VT

```

You can run the above code: <https://wandbox.org/permlink/sr9mGbWo3Lh7VrPh>
