translate C++ template into D2

[BLS]

Hi, I'd like to ask how to translate this piece of C++ source.
-code
template <class T> class Lisp;

template <class T> Lisp<T>  lisp(const T& x1);
template <class T> Lisp<T>  lisp(const T& x1, const T& x2);
template <class T> Lisp<T>  lisp(const T& x1, const T& x2, const T& x3);
template <class T> Lisp<T>  lisp(const T& x1, const T& x2, const T& x3, 
const T& x4);

-end code

further :

template <class T> Lisp<T> lispn(const T& x, int n);
	
template <class T> Lisp<T> cons(const T& t);
template <class T> Lisp<T> cons(const T& t, const Lisp<T>& list);
	
template <class T> class Lisp  ...........


eof C++
I hope it is possible to build something in D 2 by using :

class Lisp(const T..., I dunno )
Is it possible ?,  How to implement ?
Many many thanks in advance !
