为什么C++编译器不能支持对模板的分离式编译

http://blog.csdn.net/pongba/article/details/19130

备注： c++ 11引入 extern template(声明模板何时不实例话)来支持分离式编译，vs2012开始支持

分离式编译关键字export几乎不被主流编译器支持

35.1	What's the idea behind templates?
35.2	What's the syntax / semantics for a "class template"?
35.3	What's the syntax / semantics for a "function template"?
35.4	How do I explicitly select which version of a function template should get called?
35.5	What is a "parameterized type"?
35.6	What is "genericity"?
35.7	My template function does something special when the template type `T` is `int` or `std::string`; how do I write my template so it uses the special code when `T` is one of those specific types?
35.8	Huh? Can you provide an example of template specialization that doesn't use `foo` and `bar`?
35.9	But most of the code in my template function is the same; is there some way to get the benefits of template specialization without duplicating all that source code?
35.10	All those templates and template specializations must slow down my program, right?
35.11	So templates are overloading, right?
35.12	Why can't I separate the definition of my templates class from its declaration and put it inside a .cpp file?
35.13	How can I avoid linker errors with my template functions? Updated!
35.14	How does the C++ keyword `export` help with template linker errors? Updated!
35.15	How can I avoid linker errors with my template classes? Updated!
35.16	Why do I get linker errors when I use template friends?
35.17	How can any human hope to understand these overly verbose template-based error messages?
35.18	Why am I getting errors when my template-derived-class uses a nested type it inherits from its template-base-class?
35.19	Why am I getting errors when my template-derived-class uses a member it inherits from its template-base-class?
35.20	Can the previous problem hurt me silently? Is it possible that the compiler will silently generate the wrong code?
35.21	How can I create a container-template that allows my users to supply the type of the underlying container that actually stores the values?
35.22	Follow-up to previous: can I pass in the underlying structure and the element-type separately?
35.23	Related: all those proxies must negatively reflect on the speed of my program. Don't they?
