That all makes sense, I would just suggest reduce* (the reduce that requires the list to be of at least length one) as a useful word to have in the sequences library. This is mostly my own personal bias, as I've found it useful in my own code, but FWIW Haskell has an equivalent in its standard List library (foldl1).
