problem with template friend partial specialization

Show all headers | View raw

Hello!

I found some interesting case of non-compiling C++ code.
Look at first example:

--------------------------------
template<class T> void Foo(T*);
class Bar;
template<> void Foo(Bar*);

class Bar
{
    friend void ::Foo<>(Bar*);
};
--------------------------------

Compiling... All fine.

Now add to Foo return type of Baz:

--------------------------------
class Baz {};

template<class T> Baz Foo(T*);
class Bar;
template<> Baz Foo(Bar*);

class Bar
{
    friend Baz ::Foo<>(Bar*);
};
--------------------------------

Trying to compile:
MSVC: error C2039: 'Foo' : is not a member of 'Baz'
GCC: error: 'Foo' in class 'Baz' does not name a type

Is there any way to declare such friend partial specialization?
