   Thanks, tinsert and tremove are exactly what I was looking for. Looking
   at the documentation, though, i'm a little concerned, given the
   lua equivalent for tinsert. That source implies that tinsert copies
   every object at a given position(after the insert) to that position + 1,
   so that l[3] gets copied to l[4], making room for something at l[3]. 
   Doesn't this make tinsert a O(n) operation, and thus prohibitive for
   dynamic additions to large data sets?

Thanks,
Ken
