Traditionally, proponents of dynamic scripting languages have been particularly proud of their mighty one-liners, bragging about how much they can accomplish with but a few keystrokes.

Statically typed languages, on the other hand, have earned quite a reputation as painfully verbose. A meager hello world in Java, for instance, requires no less than 5 lines and 124 characters of code (a little less if you indent with tabs).

It's been said that Scala is the static language that feels dynamic. With its powerful and expressive syntax, concise yet not terse, a single line of Scala code can leverage an impressive amount of JVM power.

In this interactive, hands-on session I show you some of the most powerful and elegant Scala one*-liners that give us dynamic productivity in a static language. Ready your REPL, we are going to write some code!
