When I use another object in the .net-Framework in C# I can save a lot of typing by using the using directive.
using FooCompany.Bar.Qux.Assembly.With.Ridicul
I realize this is an old post, but I was looking for the same thing and came across this: http://weblogs.asp.net/adweigert/powershell-adding-the-using-statement
Edit: I suppose I should specify that it allows you to use the familiar syntax of...
using ($x = $y) { ... }
