In the interest of not bike-shedding this patch forever, I'll avoid commenting too much more (it already looks "good enough" to me!), but I think using "data object" outside of the DWARF context may just be adding confusion. _Personally_ I feel like "Variable" is a good term, since the information here explicitly applies to just "variables" and not really to constants, but ultimately I put my vote for either "variables" or "variables and constants".
