Powershell closures

As a follow up to the previous article, I needed to warn you (and me) about powershell closures. They didn’t work as i expected

The confusion point for me was that $Foo can be changed by the invoker, unless we add the .GetNewClosure().

As in the previous article the parameter name $ResourceGroupName is very common, it’s best to always use the .GetNewClosure() on the ScriptBlock
