I am afraid you'll have to define the exact same function yourself, if you
really want to use it. As you probably already know, you can copy it from:
http://hackage.haskell.org/packages/archive/containers/0.4.0.0/doc/html/src/Data-Set.html#splitLookup

I am not sure as to why it was not exported though. If you describe your use
case, maybe you can convince people to make a change, or people can suggest
you some other function which fulfils your requirements in some other way.
