Who hath merged this wretched code?

When the Scala compiler doesn't help

May 2, 2017 scala

Much of Scala’s power comes from its flexibility and generality as a language. You can mold it quite extensively to suit your particular problem domain or coding style.

This is a bug/curiosity in PowerShell that I stumbled upon a few years ago, but never wrote up. The behavior hasn’t changed significantly in the intervening verions, so now I’m finally getting around to a quick blog post.
