Not a bad one-liner. For all I complain about dynamic languages, they can sure be handy.

What would this look like in Scala (which also has a handy REPL)? Almost a one-liner, if you don’t count the import:

Scala will never be a popular scripting tool, obviously, but it’s cool that you can achieve a Ruby-like level of compactness with it.
