Maybe plan_err_obj or plan_datafusion_error?

Can you please document in comments what $NAME and $NAME_RAW are and how they are different?
my reading is that the raw is the name of an internal macro that gets generated. I think it would help to document more clearly what the difference in plan_err! and plan_err_raw! did (specifically that plan_err returns an Err(plan_err_raw)
