Class nested inside a template class as template function argument type

[claudiu]

Hi,

I run into a bit of trouble trying to compile the code below.

template<typename T>
struct Out
{
struct In{};
};

template<typename T>
void use(const typename Out<T>::In& r){}

void test()
{
use(Out<int>::In());
}

Using Comeau compiler I get the error:

line 13: error: no instance of function template "use" matches the
argument list
The argument types that you used are: (Out<int>::In)
use(Out<int>::In());
^

It looks like the template function use cannot deduce the argument
type but I can't understand why. Maybe someone out there can shed some
light on this?

Many thanks,
Claudiu

Try comp.lang.c++ instead.

Ooops, that's what I meant to do. Sorry.
