Thank you very much for pointing this file! As I checked this is another
structure: here there's a simple list, while in pgbench we should know
if the list is sorted and the number of elements in the list. How do you
think, is it a good idea to name a variables structure in pgbench in the
same way (VariableSpace) or it should be different not to be confused
(Variables, for example)?
