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;
}

That's ugly.

That's all there is.  Structs do not have inheritance, only alias this.
