Comment (by djowel):

 Originally,  Fusion algorithms are pure FP style const non mutating. Why?
 because they are held by reference and when you concat/build compound
 algos, my thinking was that it would be weird to have some of the algos
 mutate the sequence.  Slowly, non const versions crept in. People kept on
 asking. I guess it's time to break free from the design and have all
 fusion algos take const and non-const sequences.
