namespace templates

[Srini]

Hello all,

I was just wondering why there are no namespace templates in C++. For
instance, something like this...

template <typename TYPE>
namespace SOME
{
TYPE *pointer;
}

I cannot think of any use of this sort of a construct. But since a
class name itself becomes a namespace and when I'd have only static
data in a class, I could make it a namespace template.

Pardon me if this whole question is stupid - I just wanted to know if
it was a language design decision to not include it or no one thought
about it or its utterly useless.

Thanks is advance.
Regards,
Srini

1. If anything in such a namespace is not supposed to be generic then you
are repeating unnecessarily.
2. You have to instantiate everything in such a namespace even if you are
just using a few of them.
3. Everything in such a namespace must accept the same argument list.
