Given a list of lists, a common Racket idiom to transpose the lists is (apply map list list-of-lists). This transforms '((1 2 3) (a b c) (x y z)) into '((1 a x) (2 b y) (3 c z)). This pull request adds a transposing transducer that generalizes this operation to any sequence of sequences, allowing one to transpose a list-of-sequences into a vector-of-vectors, for example.
