Not sure it's what you're after, but in VB Whidbey we're introducing a Continue statement, that skips directly to the next iteration of a loop. As in:

  For i As Integer = 1 to 10
    While x
      If somecondition Then
        Continue While
      End If      
    End While
    If someothercondition Then
      Continue For
    End If
    ' do some other stuff
  Next i

When you hit the "Continue While, you skip directly to the next iteration of the While loop. Likewise, the "Continue For" skips everything after it and goes to the top of the For loop again.
