The PowerShell pipeline unwraps collections. Let's write a function to test to see if something is a collection

function Test-Collection {
  param(
    [Parameter(Mandatory=$true,ValueFromPipeline=$true)]
    $InputObject
  )
  process {
     $InputObject -is [System.Collections.ICollection]

The whole point of using ValueFromPipeline (and ValueFromPipelineByPropertyName) is to replace this syntax:

"c:\windows","c:\Program Files" | ForEach-Object {
  Get-DirectoryFileSize -Directory $_
}

With this synax:

gpduck

function New-Node {
	[OutputType("Whatsupduck.Powershell.GraphViz.Node")]
	param(
		[Parameter(Mandatory=$true)]
		[ValidateNotNullOrEmpty()]
		[String]$Name,
		
		[Parameter(Mandatory=$false)]
