Thanks for the response.

In the meantime, I also hacked together a simple version of what I 
needed (see below), but I'll look into the references you provided as 
well :)

void forall(alias func, size_t lvl=0, T...)(T args) {
    static if (lvl == args.length) {
        func(args);
    }
    else {
        foreach (e; args[lvl]) {
            forall!(func, lvl+1)
                   (args[0..lvl], e, args[lvl+1..$]);
        }
    }
}
