Second thought: The shorthand is also useful with an ARRAY-COPY procedure (with semantics analogous to STRING-COPY and VECTOR-COPY). These calls would have the same result: (make-array #(0) 100 100) (array-copy #100x100((0)) The second sequence isn't any shorter, but some folks may find it more intuitive. -- Bradd W.
