Lambdas in Salesforce Apex

Question

Does Apex support the concept of lambdas?

Ultimately, I am trying to DRY up some really repetitive code in my tests, so I'd love to be able to pass functions around, something like this (C#-esq).

public static TestMethod void some_test_method(){

  Arrange( ()=>

    // some setup stuff

  );

  Act( ()=>

    // test action

  );

  System.assertEquals(...);

}

Apex doesn't have lambdas, it also doesn't have anonymous classes. You'll have to compulsorily stick to declared classes. Apex doesn't support Java interfaces and abstract classes.
