+dealing with large/ nested structures, as in machine learning and
+optimisation.  For large machine learning models it can be cumbersome or
+inefficient to work with parameters as one big, flat vector, and structs help
+in managing complexity; but it is also desirable to easily operate over all
+parameters at once, e.g. for changing precision or applying an optimiser
+update step.")
