After all, it was raised, and it can even be caught by the programmer (inside del).

The word doesn't literally mean the exception itself was unraisable. It means it was raised, we caught it and we're writing it to stderr because we can't raise it again.

The relevant C API function is just called "PyErr_WriteUnraisable", not "PyErr_WriteUnraisableButThatIsTechnicallyWrongSinceItWasAlreadyRaisedAndWeJustCaughtItAndAreNowReportingItToStdErr".

Cheers, Nick.

Regards Antoine.
