Well, it would work well when unpack results are assigned to individual
vars:
x,y,offset=unpack( "ii", rec, offset)
but it gets more complicated if you have something like:
coords=unpack("10i", rec)
How would you pass/return offsets here? As an extra element in coords?
coords=unpack("10i", rec, offset)
offset=coords.pop()
But that would be counterintuitive and somewhat inconvinient..
