    I like the idea of having good utilities.
    
    There is always a bit of a trade-off between having the right utilities, and adding so
many functions that the API becomes to cluttered and hard to use.
    
    There is also the possibility to have something like a "lib" package of common functions,
that one can then simply use. Not quite as convenient as having a function on the `DataSet`,
but also prevents overloading the core set of data set operations too much.
