Why can't templates be declared in a function?

Question

Reading C++ Templates: The Complete Guide and it says

Note that templates cannot be declared in a function

It does not give e

Answer 1

It means you cannot do something like the following

  void foo()
  {
       template  //Error
       T something;
  }

Template declarations are only permitted at global, namespace, or class scope. :)

What is the reasoning behind it?

It is not allowed because the Standard says so .

ISO C++-98 (Section 14.2)

A template declaration can appear only as a namespace or class scope declaration.

Does that make sense?
