It seems rather fundamental to be able to compose a new struct from a
given struct using inheritance. Why is this not allowed?

struct slist_node
{
     slist_node* next;
};

template<class T>
struct slist_node<T>: public slist_node
{
     T data;
};

Something that has basically that effect is allowed, just not with that syntax:

struct slist_node(T)
{
     slist_node base;
     alias base this;

     T data;
}

Wow, I find it strange that we came up with the almost the same code ;)
