Summary of the new feature/enhancement

The C# language provides a convenient syntax that ensures the correct use of IDisposable objects. I believe this would be a great addition to the PowerShell language, as the 'Using statement' simplifies the code that you have to write to create a resource and then finally clean up the object.

Without the using statement you are required to ensure that Dispose() is called, then followed by the Close() method. By implementing the 'Using statement' you can assume that all kinds of streams are getting closed.

I would like to see the PowerShell language use a similar syntax to C#, which would be using (expression) statement.
PowerShell does make use of the $using variable, but I don't believe adding the 'using' keyword will cause any issues.

using ($read = [system.io.StreamReader]::new('C:\tmp\test.txt')) {
    $read.Read()
}
