I would like to suggest adding a clear command (not function) to Python.
It's simple purpose would be to clear the REPL screen, leaving the >>>
prompt at the top left of the screen.
This is something very basic but also very useful for newbies learning
Python from the REPL.

Hello,
In other interpreted programming languages the clear screen command
(whatever it is) also does not clear the session.
It just clears the screen clutter.
As I said, this would be very useful for newbies, which don't know
anything about usercustomize or sitecustomize.

Hello,
OK, I didn't know that option. Thanks.
May I suggest adding a notice to the Windows Python Installer alerting

On the other hand, maybe instead of a p

Windows 10 added VT100 support to the console, so you can create a
little cls() function to clear the screen:
cls = lambda:
Hello,
I know about those IPython commands and I searched and found several
possible solutions to clear the screen in the CPython REPL, but all are,
in my opinion, complex for a newbie.
The existence of a clear command would be simple and obvious, therefore

It seems like this could be something similar to `functools.total_ordering`
and decorate a class. In principle that transformation could go in either
direction, but only if the decorator is used.

The fallback you described would be a change in the behavior of some
working programs. Moreover, it would only affect custom classes where
adding a decorator is an option (even in external code, you can use
`MyThing = total_divmod(library.MyThing)` under this option.

I am using declarative testing a lot and I found out why unit tests are so
clunky. The reason why assertEquals(a,b) is used is because if we put
`assert a==b` then nose can catch the AssertionError but wont find out what
was returned or expected. This could be easily overcome if we allow
oveloading
