According to draft of C++11 (I have no final version):

Pointer literals [lex.nullptr]
The pointer literal is the keyword `nullptr`. It is a prvalue of type
`std::nullptr_t`. [ Note: `std::nullptr_t`
is a distinct type that is neither a pointer type nor a pointer to
member type; rather, a prvalue of this type is
a null pointer constant and can be converted to a null pointer value
or null member pointer value.
