In that case, just use echo(U)() { ...}, like this:
import std.stdio;
class Foo(T,R...) : Foo!(R) {
public void print(){
writefln(T.stringof);
super.print();
}
public void echo(U)() {
writefln(U.stringof);
}
}
class Foo(T){
public void print(){
writefln("end: " ~ T.stringof);
}
public void echo(U)() {
writefln(U.stringof);
}
}
void main(string[] args){
auto test = new Foo!(int,float,double,short,byte)();
test.print();
test.echo!double;
test.echo!short;
}
What's your global goal with this construction? What are you trying to achieve?
