not keywording the instance nominal values by default due to performance
...
On large datasets if you use dataset-as-maps too much time is taken up
in interning the nominal values time and time again. For the vast
majority of use cases string values should be fine. If we were in
clojure-land 100% then keywords would be the better option.. but we
aren't.
