You know that (map f seq1 seq2) means call f with one argument from seq1 and one from seq2 in turn, until one of the sequences has been exhausted? Does => (map #(vector %1 %2) [1 2 3] ['a 'b 'c]) ([1 a] [2 b] [3 c]) Seem like the result you would expect or not, when you talk about "run over several sequences in parallel"?
