On MSVC, the following correct code produces error C2896: 'void operator ||(T,void (__cdecl *)(tag<X>))' : cannot use function template 'void bar(tag<X>)' as a function argument.
struct foo { };
template <int X> struct tag { };
template <int X> void bar( tag<X> ) { }
template <class T,int X> void operator||(T, void(*)(tag<X>)) { }
int main() { foo()||bar<1>; }
My goal is to have an operator|| overload that deduces tag<X> implicitly, but without using parenthesis, that is, foo()||bar<1>() wouldn't be satisfactory. Doesn't seem possible, but still I decided to ask. Any ideas?
Does putting an address-of operator in front of bar help?: foo()||&bar<1>; I don't have msvc handy to try it. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) iEYEARECAAYFAkqzgZcACgkQ5vihyNWuA4UMGwCg0GRNNW8IY6r0Vv1pxho+wLDt aYIAn02VTX7HrJZuxTzby+QsgKl2XVKw =G5Nh -----END PGP SIGNATURE-----
