Formal comment #104 (enhancement) Add bytes-fill! procedure analogous to vector-fill! Reported by: Arthur A. Gleckler Component: bytes Version: 5.91 In <11. Bytes objects>, there should be a bytes-fill! procedure analogous to vector-fill! . One provided by the implementation could be much faster than one implemented using basic byte operations. An unoptimized implementation would be trivial to write. If there is no such procedure, there shouldn't be a vector-fill! . RESPONSE: A `bytes-fill!' procedure will be added in the next draft, as proposed.
