That's what I need to know. I don't know what to put there to allow composite to be an array of arbitrary Params.

Since the thing you end up with is a template still, you have to define a new template that defines the alias you want:

template SetOfSets(T) { alias Set!(Set!(T)) SetOfSets; }

This is one place where D could be nicer. I think extending the template shortcut syntax to aliases would be nice:

alias(T) Set!(Set!(T)) SetOfSets!(T);

It works for classes, structs and functions -- why not aliases too?
