const ops_name = [ "mean", "sum", "count", "mode", "std", "var", "cumsum", "cumprod",

along with these arithemetic operations, is it feasible to support other aggregation operation of Series, like nunique, min, max?

I also need a nunique, it also seems like pandas allow you to pass an arbitrary function which would be helpful in working around gaps. While agg takes a string.
