print-all metadata lost by filter-column

[harold]

Is this expected?

user> (ds/print-all (ds/->dataset {:a (range 100)}))
_unnamed [100 1]:

After filter-column it no longer 'prints all'.

I don't think it is expected - I think this is a legit issue.

I guess in clojure this is a common thing, have to consider explicitly preserving metadata (?), not a huge deal, obviously, I can just call print-all again later if need be.
