I would prefer something like this:
----
import std.stdio;

struct List(T...) {
public:
	alias Type = T[0];
	
	Type*[] ptrs;
	
	void opAssign(Type[] values) {
		foreach (index, ptr; ptrs) {
			*ptr = values[index];
		}
	}
}

List!U list(U = T[0], T...)(auto ref T vars) {
	List!U tmpList;
	
	foreach (ref var; vars) {
		tmpList.ptrs ~= &var;
	}
		
	return tmpList;
}

void main(string[] args) {
	int a, b, c;
	
	list(a, b, c) = [1, 2, 3];
	
	writeln(a);
	writeln(b);
	writeln(c);

}
