title: What is the problem with reduce()?
body: <p>There seems to be a lot of heated discussion on the net about the changes to the reduce() function in python 3.0 and how it should be removed. I am having a little difficulty understanding why this is the case; I find it quite reasonable to use it in a variety of cases. If the contempt was simply subjective, I cannot imagine that such a large number of people would care about it. </p>
  
  <p>What am I missing? What is the problem with reduce()?</p>
