Using pydoc isn't generally a successful way of discovering an API. It
shows you too many details that don't matter. Besides our docstrings are
much terser and less informative than the Sphinx doc.

pydoc is useful mostly as a Python-specific "man" command: you know
something exists, just want to remember the details.
