Yes I know *why* it worked in Py2 -- still seems like an oversight :)
To me, comparing (multi)set-like is the only reasonable behavior there
which is what IIRC the patch did, but even without that, for a given dict,
d.values() != d.values().
So, it's not like comparison is currently unimplemented. It returns
answers, they just mostly make no sense. (And of course I know that what's
happening is we're falling back to an identity check)
