Hi,
can a userdefined conversion operator be a template - that is is the following
codesnippet legal?

struct Annie
{
    template<class T> operator T()const
    {
        return T();
    }
};

void testAnnie()
{
    Annie fromAnnieWithLove;
    std::string s = fromAnnieWithLove;
    int n = fromAnnieWithLove;
}


according to VC++ 7.1 the answer seems yes, according to VC++ 6.0 the answer
seems no (the latter compiles this code but crashs when executing it)  both
observations are of course not normative :-)

Yes, see 14.5.2/5 14.5.2 Member templates/template conversion function
and 14.8.2.3 Deducing conversion function template arguments.

thanks - I only checked 12.3 and there (much to my desparation) was no phrase
like: "yes dear Arne, you may use templated conversion operators" :-)
