Could dictionaries returned by dask.config.get also be config objects

Assuming we have the following config.

# ~/.config/dask/foo.yaml
foo:
  bar:
    baz: "hello"

I can access the deepest nested object with dask.config.get.

>>> import dask.config
>>> dask.config.get("foo.bar.baz")
'hello'

However if I do this in two steps it is not possible because the return value is a regular Python dictionary.

>>> import dask.config
>>> foo = dask.config.get("foo")
>>> foo.get("bar.baz")
None

Instead I must use dask.config.get again and pass foo back in.

>>> dask.config.get("bar.baz", config=foo)
'hello'

It would be nice if when the result for dask.config.get is a dictionary then instead it returns something which has the same behaviour.

Also interesting side note, creating the ~/.config/dask/foo.yaml file above for my small example causes the config tests to fail. Because one test does assert "foo" not in config. That lead to some unnecessary debugging 😂.

@djhoese that does sound interesting.

My immediate use case for this issue has actually gone away now. Due to some refactoring, the config is no longer nested in the same way. Although this may still be useful in the future.
