That would be a neat addition. We'd have to detect the fact that there is a `DW_AT_language_name` present (I don't think the standard mandates that both attributes be present). Although it would be weird to have a version without a name. Might be worth asking the committee to clarify.

Either way, I'll do it as a follow-up. For now I wanted to just get the minimal dwarfdump support for testing these attributes
