Not a list, so why try to make a list out of it?

If they are not the same length in the original set of triples, then you 
have to truncate them somehow.  If they are the same length, then you 
don't need to do anything special.  Either way, I don't see this as 
anything that needs list characteristics.  The list-ness of the data has 
nothing to do with how you fill a table with it.
