[Moved to DR at October 2002 meeting.]

Proposed resolution (10/01):

Add to the end of 9.2.3 [dcl.fct.spec] paragraph 3:

If the inline specifier is used in a friend declaration, that declaration shall be a definition or the function shall have previously been declared inline.

Notes from the 04/01 meeting:

The consensus agreed with the suggested resolution. This outcome would be similar to the resolution of issue 136.

There is currently no restriction on the use of the inline specifier in friend declarations. That would mean that the following usage is permitted:

    struct A {
        void f();
    };

    struct B {
        friend inline void A::f();
    };

    void A::f(){}

I believe this should be disallowed because a friend declaration in one class should not be able to change attributes of a member function of another class.

More generally, I think that the inline attribute should only be permitted in friend declarations that are definitions.
