Hi.

=C2=A0 =C2=A0I f= ound a number of situations where the ability to templetize namespaces woul= d be very useful.

My latest use case is this: I= 9;m writing a library that is configured through a number of (non-type) tem= plate arguments. Such configuration affects to all the classes of the libra= ry. To be more specific, it's a fault-tolerant library for the aerospac= e industry where the whole library is tuned with some integers (some of the= n 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:

=C2=A0 =C2=A0 using namespace TheLibrary<arg1, arg2,= arg3>;

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

Thanks,

=C2=A0 =C2=A0Daniel.

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