Re: [Haskell-cafe] Help wanted: Lazy multiway zipper with mismached intervals

Hello,

I need to zip together multiple lists.

I would write a function 'merge' which merges two lists. Multiple list can be merged with 'foldl merge []'.

The lists are sorted by date, and each entry in the list represents data for a time interval. The time intervals between the lists may be missmatched from each other.

This sounds like the merge step performed in Haskore which merges two sequences of time-ordered (music) notes. With absolute time stamps: (search for 'merge') http://cvs.haskell.org/darcs/haskore/src/Haskore/General/Utility.lhs With relative time stamps: http://cvs.haskell.org/darcs/haskore/src/Haskore/Performance.lhs
