>
> Currently, the {{ValueVector#getObject}} API supports covariance for
> primitive types.
> For example, {{IntVector#getObject}} returns {{Integer}} while
> {{BitVector#getObject}} returns {{Boolean}}.
> For complex types, we should also support covariance. For example,
> {{ListVector#getObject}} should return a {{List}}
> This will help reduce unnecessary casts, and enforce type safety.
