-pedantic too pedantic about templates

No, the code is ill-formed.

This is a dependant name, so Outer<N-1>::Inner is considered as an
object; the whole thing should be function call (or operator()
invocation). As it turns out, Outer<1>::Inner is a type, so the
construct is ill-formed. The correct notation would be 

   { return typename Outer<N-1>::Inner(n); }

Hope this helps,
Martin
