There is not all that much commonality; many functions don't bother to
populate all of the ArrayMetaState fields because they don't need all of
them. (The ones you quote don't, in fact.) You are either going to end
up with a subroutine that does extra syscache lookups to populate the
whole struct every time, or a confusing collection of ad-hoc subroutines.
I'm not convinced that there's a lot of mileage to be gained here.
