I had a client call me up and complain about my reduce code because it was hard to read and he couldn't tell what was going on. I broke through to him when I added comments to it that showed a particular data structure going in, and what was coming out. Once the transformation was clear, the apparent complexity was no longer a problem, leaving me to believe that the problem with reduce is almost entirely about legibility.
