A fun way to learn more about

Welcome to the Scala Puzzlers archive, the collection of Traps, Pitfalls and Corner Cases in older versions of the Scala language.

Prepare to be surprised, entertained and...well, puzzled! What is presented here is a selection of seemingly simple examples which demonstrate that there's plenty of head-scratching left in Scala. Let your mind be challenged by unexpected and unintuitive behaviour and results and learn something in the process.

Choose a puzzler from the left-hand list to get started!
