Data classes are nice, but they are not a general substitution for Properties, which address the greater getter/setter boilerplate concern. That said, you can use project Lombok for that pretty straightforwardly. You can also use project Manifold[1] to add useful features many of which Scala lacks:

* Type-safe metaprogramming (like F# type providers)

* Structural Typing

* Extension methods

* String interpolation

* Templates

* Type-safe reflection

* [Un]Checked exceptions

Interesting, I didn't know, thanks for mentioning.
