A simple sample code involving templates, friends and lookup

[Dragan Milenkovic]

Hello,

I'm aware about these issues being around for quite a while now, but
there is still a chance this sample code can be helpful. I apologize
if someone gets annoyed :-P


template <typename T>
struct Foo
{
    template <typename Z>
    friend void func(const Foo &);
};

void check(const Foo<int> & x)
{
    // Foo<int> weird;  // uncomment this line and all works

    func<int>(x);    // <-- ERROR
}


Tested with gcc 4.0 - 4.3, and all behave the same:

"error: ‘func’ was not declared in this scope"

but it works if you uncomment the weird line.


Best regards,

Dragan Milenkovic
