Is changing the signature allowed? Because it *must* be changed (at the very least to accommodate the exceptiontable, but there are several others too -- your PEP 657 touched it last to add endlinetable and columntable).

I think this was a mistake in PEP 387 and we just need to retract that. Perhaps it could be left as a dummy that always returns an error?

Yeah that's the crux. :-(
