We all talk about using the right tool for the job in the context of programming items. But which job? And what's the right tool for it?

I want your help in determining the answer for this.

Scala is a general purpose programming language designed to express common programming patterns in a concise, elegant, and type-safe way. It smoothly integrates features of object-oriented and functional languages, enabling Java and other programmers to be more productive. Code sizes are typically reduced by a factor of two to three when compared to an equivalent Java application.
