The docs for the inspect module and the types module do not list all the import-related module attributes.  I'm guessing they've been out of sync a while.

The docstring for for inspect.ismodule() is likewise missing information.

Are they still missing? inspect.ismodule() seems to be there at least.
https://docs.python.org/3/library/inspect.html

As far as I can tell there is at least some information missing from the 'Types and members' section. Not all attributes are listed in the table. 

For example the attribute __cached__ is missing from the module type but it is documented in the inspect module. 

I can update the docs but I would rely on the comments in Lib/inspect.py on what to include. Executing inspect.getmembers on a module returns a lot more attributes than documented in ismodule.

The relevant module attributes are described in the importlib docs: https://docs.python.org/3/library/importlib.html#importlib.abc.Loader.load_module

I can help too.

@emmanuel: thanks for offering your help. 

I made a first attempt at improving the docs in this branch: https://github.com/MichaelAnckaert/cpython/tree/bpo-19820
