I love the simplicity of your example. Perhaps it would be even easier to understand if n had a value in example or leave out n entirely:

“1234567″.map(n2s).mkString(” “)

That’s a minor detail that didn’t keep me from sharing your excitement with this feature of Scala. I did not know that maps are also functions, I’ll have to keep my eye out for hidden treats like this in the future.

Thanks for posting this!
