> Scala programs usually are comparably easy to debug and run as expected as soon as they get compiled successfully.
I wholeheartedly disagree. Scala is among the most difficult languages to master. From experience, a successful compilation do not shield you from bugs and runtime exceptions. NullPointerException being my favourite, as a reminder that lots of libraries are built on top of Java's ecosystem, and thus plagued with the same curse.
And even if you're toying with pure Scala code, without any dependencies, it's still possible to end up in a state where the given traceback would be absolutely useless and full of (Anonymous) calls. Good luck with that.
