Why aren't template specializations allowed to be in different namespaces?

Question

Please, see what I am trying to do:

#include 
namespace first
{
 template 
 class myclass
 { 
  T t;
 public:
  void who_are_y         


        

Answer 1

It complicates things:

namespace first
{
  template  class TArray;
}

namespace second
{
  using first::TArray;

  template  class TArray < Node >;
  //                              ^
  // Only there do you realize it's a specialization and not another template
}

I understand your frustration, I often wished for the same thing. It seems definitely possible and I certainly don't buy the logical grouping argument, however I must admit that it would require even more effort from the compiler writers, and parsing C++ correctly is already difficult enough as it stands.

Templates are a bit messy in C++ if you want my opinion, but then it's easy to say with the benefit of experience and after having seen 20 years of use :)
