Creating/Working With Nullable Objects in PowerShell - How?

Hi,

how do I create and work with Nullable objects in PowerScript.

None of the tips I found worked:

> ([System.Nullable[System.Int32]]1).GetType().Name
Int32

> ([System.Nullable[System.Int32]]$null).GetType().Name
You can't call a method on a null value expression.

> (New-Object System.Nullable[Int32] 1).GetType().Name
Int32

Any help is appreciated!
