As you probably already know, you can copy it from: <a href="http://hackage.haskell.org/packages/archive/containers/0.4.0.0/doc/html/src/Data-Set.html#splitLookup">http://hackage.haskell.org/packages/archive/containers/0.4.0.0/doc/html/src/Data-Set.html#splitLookup</a><div>
<br></div><div>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.<br>
