Daniel,

I agree with you.

Hi.

   I found a number of situations where the ability to templeti= ze namespaces would be very useful.

My latest use = case is this: I'm writing a library that is configured through a number of = (non-type) template arguments. Such configuration affects to all the classe= s of the library. To be more specific, it's a fault-tolerant library for th= e aerospace industry where the whole library is tuned with some integers (s= ome of then related to redundancy due to ionizing radiation).

The most natural thing would be to put all the classes = in a namespace, and let the namespace be templetized with such arguments.
Moreover, a using namespace with the appropriate arguments would s= uffice for all the application. For example:

    using namespace TheLibrary<arg1, arg2,= arg3>;

I didn't write the proposal yet, since = I'd like to get some feedback.

Thanks,

   Daniel.

ps: The librar= y will be available soon and uses template metaprogramming based on the arg= uments.
