So I'd go for something like (bitwise-and \1001 \0110) => \1111 Alternatively, you could regard bitstrings as a kind of vector and read/write them using vector syntax. In that case you'd have (bitwise-and #(1 0 0 1) #(0 1 1 0) ) => #(1 1 1 1) which is how common lisp does it. But Common Lisp has typed-vector infrastructure we don't. And suddenly, typed vectors bring us back to the current SRFI-47. Should au1 be added to the set of vector types for SRFI-47, with bitwise-operations and bitstring<->integer conversions defined on bit arrays in a following SRFI? Bear
