PowerShell and delegates

At my current project, we have written a lot of PowerShell. We came to discuss whether, we can use delegates in PowerShell or it is a pure C# (.net) thing. The short answer is yes, you can do it. The syntax is like this:

1 $url = "http://win-l2sfc3oetnn"
2 function GetSiteElevatedPrivileges
3 {
4     $site = new-object "Microsoft.SharePoint.SPSite" $url
5     write-host $site.RootWeb.Title
6 }
7 [Microsoft.SharePoint.SPSecurity]::RunWithElevatedPrivileges(${function:GetSiteElevatedPrivileges})
