Does Fluent-Hibernate exist?

Is there something like Fluent-NHibernate for the 开发者_如何转开发original Java Hibernate? If not, why not? Are there any language-specific limitations?

I believe Fluent-NHibernate relies on the nice features provided by Linq in C#3.0 if I'm not mistaken. Until Java implements lambda expressions etc I don't think we'll see Fluent Hibernate.

I could be wrong though. :)

Groovy supports lambda expressions (although they rather confusingly call them closures), and Groovy classes are directly accessible from Java. Perhaps the mappings for Java apps could be written in Groovy.

Just a thought.

Scala supports lambda's, right (I'm totally Scala newbie). And it is completely inter-operable with Java at the static compilation level. It seems like Scala+Hibernate would enable fluent on the Java side.
