Hmm. But there are boatloads of places where we call IsA on a
pointer of type Expr *, or sometimes other things. Why aren't
those triggering the same warning?

Perhaps. That's a bit sad because it's piercing a layer of
abstraction. I do not like compiler warnings that can't be
gotten rid of without making the code objectively worse.
