Should I have made this implement Seqable as well? It wasn't clear to me, because as far as I could see this was the only function in clojure.core.reducers that's generating a brand-new sequence rather than transforming an existing one.

Previous version neglected to include the seed value of the iteration in the reduce.

Currying iterate seems useless, albeit not harmful.

While implementing repeat, I couldn't use currying. Because 1-arity is already reserved for infinite repeat ([n x] and [x], not [n x] and [n] if currying)

How about we just support currying for functions where last param is reducible?

This new patch replaces the previous patch. As requested, I am splitting up the large issue CLJ-993 into smaller tickets.

Does not depend on any of my other reducer patches, but there will probably be some minor merge conflicts unless it is merged after CLJ-1045 and CLJ-1046, and before CLJ-993.
