Are you sure about that? I haven't seen it.

Code *inside* the core can play any dirty tricks it likes, because we
guarantee to keep it working as things change across releases. But, AFAICT,
we have no evidence that anything outside the core abuses this stuff.

I still doubt it matters to anything outside the core.

You're talking about a function that doesn't exist now, right (I don't
recognize the name PyString_Intern, and neither it nor
PyString_InternReference scream anything obvious to me)?
