My comment is just on the name. I'd expect something named `groupby` to behave essentially like Mathematica's `GatherBy` command. http://reference.wolfram.com/mathematica/ref/GatherBy.html
I think you are after something more like Matlab's grpstats: http://www.mathworks.com/help/stats/grpstats.html Perhaps the implicit reference to SQL justifies the name...
