In parallel with this evolution, other languages have popped up with their own sets of features (and often with more freedom to experiment than Java). Some of these features have made their way into Java, others will be added eventually, and others may continue to be debated for quite some time.<br> This article is written from the perspective of a Java programmer (and teacher) who also writes plenty of Scala (and a few other languages). Through code examples, it discusses a few of the features I miss the most when returning to Java, namely inferred semicolons, tuples, named arguments, local functions, tail-recursion optimization, type aliases, opaque types, and variance annotations.</p>
