As Chris said, use_iterator walks over the Use objects now, not over the
User objects.

Sadly, a Use *implicitly converts* to the used value. IE, directly back to
the Value you called 'use_begin()' on. That is why this assert is firing. =[

If you want to walk the Users which Use an object (rather than the Use
nodes that connect them) use the newly minted Value::user_iterator (or a
range based for loop over GV.users()).
