Expectation

What the title says. ValDefMethods has a tpt member but it is missing from DefDefMethods. I was also thinking whether it would make sense to have a ValOrDefDef common super type for ValDef and DefDef (I find myself often writing ValDef | DefDef). This would hep abstracting over the common members, i.e., tpt and rhs.

DefDefMethods has returnTpt.

Adding ValOrDefDef with tpt and rhs makes sense. In that case we would not require DefDefMethods.tpt.
