FWIW, this agrees with the specs in _abcoll which show KeysView and ItemsView

(commenting on a closed bug, because I'm not sure it should be re-opened)
While coming up with examples, I found a weird inconsistency. Was it
intentional for viewkeys() and viewitems() to support set operations, but not
viewvalues()?

The fix is easy, I think; just add Py_TPFLAGS_CHECKTYPES to the
PyDictValues_Type's definition.

Why do you expect dict_values to support set operations? Dict values unlike
keys are not sets, they are more like lists. Set operations of dict_values are
not supported in 3.x either.

Ah, of course! It didn't occur to me that .values() isn't necessarily a set.

The patch looks fine. I verified that the new tests pass on trunk and py3k. I
am attaching a patch for py3k with a forward port of set opereations and repr
tests.

I found the issue. The view types didn't have Py_TPFLAGS_CHECKTYPES set, so the
types were using the old-style binary operators.
Here's a patch that fixes the issue. Please review.

It is a bug.
First, the dictviews_as_number is broken; the field for classic division was
removed in 3.x, so everything is shifted by one. I included a patch to fix this.
Unfortunately, this isn't enough to fix the issue. There
