Due to the recent drafts, are templates legal in friend declarations?
A rough example:


class HideStuff {
private:
    int undersurveillance;
public:
    friend
 template<class CvtType>
 CvtType convertit(HideStuff const&, CvtType);
};


// Example definition of convertit() - doesn't matter here
// template<class CvtType>
// CvtType convertit(HideStuff const& hs, CvtType) {
//     return T(hs.undersurveillance);
// }



I've checked the April 95 DWP, but it doesn't say anything particular
about this case. My compiler doesn't accept it, but I don't know
whether it's actually legal or not. Has this been clarified recently?
It should be.

I think templates in friend declarations would be quite a useful
feature, and it'd be a shame to let them out, especially since
templates are already allowed for members.

Yes (and supported at least by recent EDG-based compilers), but the
`template<...>' prefix comes first:


class HideStuff {
private:
    int undersurveillance;
public:
    template<class CvtType>
    friend CvtType convertit(HideStuff const&, CvtType);
};

I'm pretty sure it does. I don't have the April 95 version anymore,
but it was towards the end of chapter 14 --- 14.11 or 14.12 perhaps.
