Yes, it can; or as a J non-uniform array as a singleton argument. One of the areas not explored fully by the 1978? article was the effective clustering of control flow; similarly here, you want to have the restructuring suggest minimally connected clusters within the data: you only use a structure when similar connectives are present for all scalars. (a structure in other languages).
