thinking about it a bit more, it would certainly make sense to return a
seq with all the identities. Then I can just ask for the first...hmm
interesting :)

Can you give an example use case?
sure... sometimes I do something this:
(map (if even? (fn [num _] (identity spans)) str) some-seq1 some-seq2)
but I'd like to write this instead:
(map (if even? identity str) some-seq1 some-seq2)
Personally, I would be a little surprised to find out that identity
worked like this. After all, why return the first argument, why not
the last? Or a vector of all the arguments?
the idea is to we keep the same semantics as we currently have...
