Handling position-only arguments

[thorwhalen]

I've tried this with object dispatching:

backend_store = {
    'some_key': b'some_value',
    'some_other_key': b'some_other_value',
}

handlers = [
    dict(
        endpoint=backend_store,
        name='backend_store',
        attr_names=['__getitem__', '__setitem__'],
    ),
]

Can't use this because the two methods have only positional-only arguments, and the protocol is:

url = 'http://localhost:3030/backend_store'
add_args = {
  "_attr_name": '__getitem__',
  "key": 'some_key'
}
requests.post(url, json=add_args).json()

Maybe this is a general problem (need to try functions with positional only arguments).
