// 間違い等があれば指摘してもらえればと思います。
// 以下の2行はnon-blockingな処理
val f1 = actor1 !!! msg1 // actor1 に msg1 を投げ、Futureを得る
val f2 = actor2 !!! msg2 // actor2 に msg2 を投げ、Futureを得る
// この時点では actor1, actor2 の処理は終わっていない

inheritance or mix-in?
// There's a class called MappedPassword in Lift. I wanted to create a class that
// holds the plain text when a password is set.
//-------------------------------
// This works, but I didn't like the idea for two reasons.
// 1. The class name is long.
// 2. Seems kinda ugly to me.
abstract class MappedPasswordWithPlainWhenSet[A<:Mapper[A]](override val fieldOwner: A)
extends MappedPassword[A](fieldOwner) {

Extending CRUDify, but this won't compile...
/**
* コンパイル通りません。
*
* やりたい事：
* 1. ProtoUserクラスを継承した任意のクラス(仮にUser)と、モデルクラス(Foo)の2つが存在。
* 2. Fooには、どのユーザーがレコードを作成したかを表すフィールドがあり、Userテーブルへの外部キーとなっている。
* 3. レコードの所有者のみがCRUDの機能を使えるよう。
* 4. 2, 3の機能はtraitにして、Foo以外のクラスでも同様の機能を使えるようにしたい。
*
* Liftのソースをにらめっこしながら頑張ったんだけど・・・
