> In RangeEqualsVisitor, there are overload methods for both super class and
> sub class. This will lead to unexpected behavior.
> For example, if we call RangeEqualsVisitor#visit(v), where v is a fixed width
> vector, the method actually called may be visit(ValueVector), which is
> unexpected.
> In general, in the visitor pattern, it is not a good idea to support method
> overload for both super class and sub-class as parameters.
