Whoops, responded privately (and also made a mistake I wanted to correct, so I guess that works out). To the list this time:
I don't like using the 'zip' terminology here; I feel like that should be reserved for multiple distinct data sources.
Why not 'map2'?
I too dislike the "zip" terminology here, for the same reason. But I also I mislike "map" since this isn't functorial in any particular way (I'd expect "map2" to have to do with some sort of 2-functors). I'm agnostic on adding the function vs not, but If we're bikeshedding for short names how about "twine"? (The problem I see with "pairwise" is that it's ambiguous about whether values get "reused": i.e., matching even elements to odds[1], vs matching every element to the next/last.) [1] I also note without comment that this interpretation is the inverse to what is traditionally called "zip" in the non-wellfounded set theory community; e.g., when viewing streams (like the Thue–Morse sequence) as a greatest solution to a system of equations. -- Live well, ~wren
