I have a template class which has 2 class template parameters.
The class has a member function which has a template definition
which handles the general case. I want to define a partial
specialization for this member function which will deal
with those cases in which the 1st parameter is a fixed type (=int).

The compiler that I am working with gives me an error message
when I do this, unless I also write an analogous partial
specialization for the template _class_.

What does the standard say? Can I write a partial specialization
for a member function without partially specializing the class
that it is a member of?

Thank You.

Two points of view:

(1) Specializations of nested template classes or nested member
functions is never allowed.  Eg,
   template <class T> struct A {
      template <class U> void f(U) { ... }
      template <> void f<int>(int) { ... } // error
   };
   template <class T> template <> void A<T>::f<double>(double) { ... } // error

(2) Specializations of nested template classes or nested member
functions are allowed only in the class definition.
   template <class T> struct A {
      template <class U> void f(U) { ... }
      template <> void f<int>(int) { ... } // ok
   };
   template <class T> template <> void A<T>::f<double>(double) { ... } // error
