Seems pretty easy to me. It has to be a dunder, or a sunder at least,
because regular non-underscore names are reserved for the enumerations
themselves.
How do you programmatically get the information about which encoding
error handlers the `open` function takes?
I don't know how to get them programmatically, but today I learned how
to get them from the documentation:
* Start with help(open)
* Page down two pages.
* import codecs
* help(codecs.Codec)
That gives you the predefined error handlers, assuming the docs are up
to date. I still don't know how to find out what extra handlers have
been installed.

Okay, so if the API is (say) this:
def median(data, *, nans='ignore'):
...
will iPython give you a list of all the other possible strings that are
accepted? How does it know?
