How to define a template member function of a template class

template <typename T>
template <typename T2> 
void Foo<T>::Bar(const T2 * t) {
    // ... this is where I'm tearing my hair out ...
}

Ugly isn't it.

template<typename T>
template<typename T2>
void Foo<T>::Bar(const T2* t) 
{
     // stop tearing your hair out
}
