> When one defines an extension type in Python (by subclassing {{PyExtensionType}}) and uses that type e.g. in a Arrow table, the printed schema looks like this:
> {code}
> pyarrow.Table
> a: extension<arrow.py_extension_type>
> b: extension<arrow.py_extension_type>
> {code}
> ... which isn't very informative. PyExtensionType could perhaps override ToString() and call {{str}} on the type instance.
