Is it a library type though?  I am not sure there is clear 
distinction between language and library in C++. So you can have 
"library features" that are implemented using intrinsics, which 
might make them language-features if they cannot be done within 
the language in a portable fashion. It is kinda hard to tell 
sometimes, maybe the huge spec makes it more clear, but it is at 
least not obvious to me as a programmer.
