[Swift-devel] dataset terminology

[Ben Clifford]

The HPDC paper in SVN contains (in the language section, which I am 
porting to the user guide):

>  We often refer to instances of composites of
>  mapped types as \emph{datasets}.

Is this intended to mean that:

  file f <"mydata.dat">;

is not a dataset?

In the implementation, pretty much everything is a dataset, in the sense 
that it is represented by an instance of the DSHandle class. This includes 
primitive in-memory values such as integers and strings.
