  And now you aren't using the language, but a (very) poor subset 
of a language that doesn't even support templates.

  Duh, but every C++ compiler exposes this, so it is defacto 
standard. C++ has plenty of non-standard standards, such as 
#pragma once.

   I see on MS website an article about having a vector data type. 
While interesting that isn't the same as exposing the actual 
instructions, which will limit potential gains.
