Comment:

 We decided to add a :first and :last argument that overrides the :start
 and :end values.  This way get-instances-by-value can still map all nils.
 get-instances-by-range uses the null as first/last semantics, but nil nil
 is the same as get all.  (Thanks to Henrik for the discussion on this one)
