Describe "Koan(s) You Suggest"

There's sometimes a bit of a blurry line between loops and pipelines in PowerShell; we can expand the existing koans in AboutLoopsAndPipelines to cover some common misconceptions.

Context "The Scope of the Koans You Suggest"

  • foreach keyword v.s. foreach alias usage
  • break/continue behaviour in loops and the highly dangerous behaviour when used in a pipeline
  • clarify the function of return in pipeline contexts and how they can be used to break out of a loop early, but not pipelines.

Context "Additional Information"
