I've been tweaking the Hibernate in Scala example from my previous post.

The experiment is to interleave the hbm.xml mapping information right into your plain old scala object code. Sort of like a poor man's annotation, so you can keep your meta information right snug up to your properties.

Another whoa moment today -- ran across a pointed, concise Scala code snippet in Eric Torreborre's announcement of the specs 1.1 testing library...

 (a: Int, b: Int, result: Int) => { calc.add(a, b) must_== result }
 }
 }
}

The above is a great e… Continue
