Had the same feeling many years ago when i wanted to learn it. Bought the book of some the main creator (?) behind scala and started to read and experiment with on a weekend. But every chapter was filled with many completely different ways on how to solve something. In the end i decided that scala looks really great, but will be really problematic in a team if everything can be done on so many different styles.

It looked for me like someone wanted to add every existing language into one single language.
