Function template inside of class template

[Arne Schmitz]

Consider this:

----SNIP----
template<typename T>
class
foo
{
public:

template<typename S> void f(S s) { }
};

// ???

// template<typename T>
// void
// foo<T>::f<S>(S s)
// {

// }

int main()
{
foo<int> f;

f.f<float>(1.0f);

return 0;
}
----SNIP----

That code works, but how do I write the function definition outside of the
class? I cannot get the code to compile, always some syntax error.

The code below works:

template<typename T>
class
foo
{
public:

template<typename S> void f(S s);
};

// ???

template<typename T>
template<typename S>
void
foo<T>::f(S s)
{

}

int main()
{
foo<int> f;

f.f<float>(1.0f);

return 0;
}
