This needs to be copied into visitBinaryExpression,
visitFunctionObjectInvocation, visitRedirectConstructorInvocation,
visitSuperConstructorInvocation, and visitUnaryExpression. It might be possible
to move it into checkInvocation and cover all of those cases in one place, but I
haven't looked that deeply.
