arrays have #'array-dimentions and #'array-rank (as a matrix) and there's cool (row-major-aref my-arr index) for indexing array with single index, going throug all elements vectors have literal notation #(1 2 4 1), they are one dimentional have :element-type key in constructor, not quite sure how to use that and we can try to #'coerce list to something else by providing symbol for type, which we could get from (type-of my-vector) also literal notation for byte vectors, cool #*110011001
