I'm not really sure of the benefits.
I actually asked this because I'm not sure myself. We have two APIs: sequences and streams, but it's not entirely clear to me when to prefer one over the other. Streams support `first`, `rest`, and `empty?`. Sequences don't directly support either `first` or `rest`, but with the `sequence-ref` and `sequence-tail` functions you can emulate them. One advantage of streams is that there's now an easy way to implement them (via the `gen:stream` generic interface). Is there a guiding principle behind these APIs?
