FWIW, I'm not sure it's a good idea to design the interface around partial specialization. std::vector<> replaces almost every possible need for array allocation, so does this use case really need to be less verbose? Is it worth dropping support for older compilers?
Need to be? No. But I still like it. <shrug> I was convinced because that's how a newbie expected it to work.
I'm starting to not like it. :-) The problem is: template<class X> void f(S_ptr<X> px); where f doesn't support arrays. A reasonably common occurence. S_array<> doesn't match, but S_ptr<T[]> does. The author of f would need to learn about enable_if to prevent array pointers from being passed to f. This is not good, although the exact degree of not-goodness is somewhat debatable.
