via in instance, I mean. IMHO, it should be required to do Type.staticMember
rather than var.staticMember. The fact that it's allowed is just messy and
is one of the things that we inherited from C++ that we shouldn't have. This
case falls in the same camp, except that it's a new mistake, since C++
doesn't have init values.
