     - Ideally, data should be deterministic (i.e. __call__() should always
       return the same thing). It would probably be up to the user to be super
       careful if he decides to use a non-deterministic dataset.
+    - About the "task vs. dataset" distinction. This could be achieved by
+      associating to a task the names of the fields it requires (e.g. "input"
+      and "target" for the regression task), and if the dataset does not
+      already defines these fields, using a dataset wrapper than does it
+      (saying for instance that "input" is the concatenation of "x1" and "x2",
+      and "target" is "y", for a dataset whose fields are x1, x2 and y).
