I just posted this question at the bottom of the 1.1 blog post:

What is the reasoning behind creating onEach()? What does this give a developer that you can’t get from forEach()?

I don’t think it is clear to a new developer to the language that calling onEach() returns the iterable instance for the next statement in the chain. In the example above I would just call forEach() in the following way:

.forEach { f ->
  println(“Moving $f to $outputDir”)
  moveFile(f, File(outputDir, f.toRelativeString(inputDir)))
}
