A PowerShell, and PowerCLI, cmdlet returns objects that are placed one-by-one in the pipeline.
That pipeline passes these objects, again one-by-one, to the next cmdlet in the chain.
A calculated property on a Select-Object cmdlet allows you to specify an expression (in the E part).
That expression can refer to a nested property, or can even a complete code block.
