How do I turn this slick method into a subquery?
val myRank = (session: Session) => {
val mine = Ratings.filter(_.userId === user.id).map(mapper).
first()(session)
Ratings.filter { mapper(_) > mine }.map(_.length + 1)
}

Unity3D Mono bug when using... I don't know. Code? The line that crashes is in SceneBase.cs. This seems to be fixed in Unity 4.3.2f1

using UnityEngine;
using utils.functional;
namespace utils.rx {
public interface IObservable<out T> {
ISubscription subscribe(Act<T> onChange);
IObservable<A> map<A>(Fn<T, A> mapper);

Unity compiler is buggy
ctx => { var i = ctx._1; var bi = ctx._2; var map = ctx._3;
Log.editor("flatMap subIter skip: \n ctx=" + ctx + "\n i=" + i + "\n bi=" + bi);
Outputs:
ctx=(
Iter(Some((System.Collections.Generic.List`1[System.Int32],0,False))|sh:Some(3)),
Iter(Some((System.Collections.Generic.List`1[System.Int32],0,False))|sh:Some(2)),
System.Fn`2[System.Int32,com.tinylabproductions.TLPLib.Iter.Iter`2[System.Int32,System.Tpl`3[System.Collections.Generic.IList`1[System.Int32],System.Int32,System.Boolean]]]
