Templates and headers

Question

So do any of the future standards of c++ plan to resolve the issue of having to combine the declaration and implementation?

Answer 1

There's a very good reason why the template implementation needs to go into the header. A template is not code - it's only a template for the automatic generation of code. The code doesn't get created until you try to use it with the template parameters filled in. The compiler needs to have the full template body in order to fill in the blanks and get working code.
