But I thought we *had* gone that route. Actually, there's no "route"
to go here. We're only talking about documenting the existing
semantics that cPython has, and I thought that included no longer
guaranteeing insertion order after a delete. Although I can't prove
that by experiment at the moment.

I don't know whether my confusion above is an argument for or against
documenting the behaviour :-)
