How can I achieve something like the following? I want to create a class B that has all the interfaces of the class passed as a template parameter.

import std.trats;

interface I0 {}
interface I1 {}

class A : I0, I1 {}

class B!C : InterfacesTuple!C {}

void main() {
	B!A a;	
}

The above fails with the following error on DMD 2.064.2

You probably meant:

class B(C) : InterfacesTuple!C {}
