ok, all good then.

Yes I'm going to close as I don't think there is much actionable.

But thanks for opening the issue just in case.

Do you have any custom configuration ?

I can't reproduce so it's hard to find which object returns a None repr:

Yup, found the culprit—it's exit and quit, caused by my startup file:

type(exit).__repr__ = lambda self: self()

This "backports" IPython's behavior of quitting with just exit instead of exit() to the built-in REPL. I didn't realize IPython was also using this startup file 😄 And I guess I thought this was an IPython issue since the default REPL doesn't exit since it doesn't include exit nor quit in its globals().

I guess that makes this issue invalid?
