Oops, just realized this is a dup: http://hackage.haskell.org/trac/ghc/ticket/974 But, perhaps we can make some progress ? j. At Fri, 14 Sep 2007 13:12:41 -0700, Jeremy Shaw wrote:

This function is like unzip for a list of Eithers instead of tuples.
According to google code search, I am at least the 5th person to implement this function:
I opted for the name unzipEithers because the function is similar to two existing functions: unzip and catMaybes. It seems less similar to partition, because partition does not desconstruct the values, it just divides them into to two groups. I have no particular attachment to the name however.
I modeled the implementation after unzip and partition. Hopefully I made effective use of the irrefutable patterns and laziness, but someone else should verify.
