[jira] [Created] (ARROW-7858) [C++][Python] Support casting an Extension type to its storage type

Joris Van den Bossche created ARROW-7858:
--------------------------------------------

             Summary: [C++][Python] Support casting an Extension type to its storage type
                 Key: ARROW-7858
                 URL: https://issues.apache.org/jira/browse/ARROW-7858
             Project: Apache Arrow
          Issue Type: Test
          Components: C++, Python
            Reporter: Joris Van den Bossche


Currently, casting an extension type will always fail: "No cast implemented from extension<arrow.py_extension_type> to ...".

However, for casting, we could fall back to the storage array's casting rules?
