I and other people have asked in the NG about recursive mixins and got no
answer. Recursive mixins are probably tricky to implement but until they are
implemented or the specs clearly prohibit them, it is a bug (and major one with
respect to what I'm trying to do).

template Foos(Funcs...)
{
    static if (Funcs.length)
    {
        mixin Foos!(Funcs[1..$]);
    }
}

mixin Foos!(void function(), void function(int));

Error: mixin hello.Foos!(void(*)(),void(*)(int)).Foos!(void(*)(int)).Foos!()
recursive mixin instantiation
