Standard type traits are of course the most needed feature for library
writing. I mean traits such as is_pod<T>, is_class<T>, is_function<T>,
n_of_args<T> when T is a function, arg_type<T, N> etc. Most of them
cannot be generally implemented without core language support, so I'd
like to see standard traits in core language.
There are other desired features, like local classes for templates,
closures etc. but they are not so important for library writing as
