Description

The reduce arity of IReduce in PersistentVector is implemented as: "throw new UnsupportedOperationException()".

After the CLJ-1572 patch is applied the following code will throw:

(reduce + [1 2])

Approach taken: Implement reduce(f) in PersistentVector.

Alternative: An alternate would be to change PersistentVector from IReduce to IReduceInit and remove the reduce without init function. In this case, reducing a vector would fall back to seqs.
