[Haskell-cafe] zip3, zip4 ... -> zipn?

[Joel Koerwer]

Frank,

The return type of zipn would have to depend on the number of
arguments. If you are satisfied with all arguments having the same
type, then you can use transpose:

zipn list1 list2 .. listn  => transpose [list1, list2, .. listn]

Can we make a polyvariadic zipn that returns a [HList]? Seems like a
neat challenge, but I'm a bit pressed for time right now. I'm afraid
it would be pretty unwieldy.

I'm looking forward to seeing solutions though. :-)
