>From your extract it looks like MSVC 11 would also add:

- decltype (but for gcc not v1.1 - what is that?)

And MSVC 11.0v2 (I don't know what that is)
would add:

- variadic templates
- initializer lists
- explicit conversions
- raw string literals
- r-value v3.0 (I don't know what that is)

decltype is useful, particularly with the new function declaration
syntax.  variadic templates are tremendously useful anmd really cut down
on code bloat.  Things like the CommandLine library could _really_
shrink in size with variadic templates.
