a) I haven't encountered the need for such a component in the
pipelines I have written so far.

b) There are number of basic operations on sequenced which we could
implement with a component. See [1] for what Haskell has to offer. Our
"pack" is similar to Haskell's "zip" (except zip drops items from the
longest list). But there are a number of other components we could
provide as well, and adding just pack at this point seems somewhat
arbitrary to me.

So I don't have a strong objection to adding "pack", but would rather
leave it out for now, and add this to our virtual list of things to
keep in mind for V.2.
