Powershell -- higher order functions with arguments that take arguments

Dead simple example based on this:

	# Create a function that accepts a function that takes arguments
	Function Test ([scriptblock]$code, $name) {
	& $code "$name+$name" | % {
	New-Object PSObject -Property @{
	Name = $name
	Prop = "**$_**"
	}
	}
	}
	# Create a function to call
	Function Set-Lower ([string]$x) {
	$x.ToLowerInvariant()
	}
	# Create a suitable script block to wrap the function and take a parameter
	$b = [scriptblock] { param([string]$Target = "PARAM") Set-Lower $Target }
	# Invoke the Test function passing it a scriptblock and argument
	Test $b Junku

Junku                                                 **junku+junku**
