Sounds good to me.

New question: It seems that strict typeof would give the same result as the
above. Then what do you need strict typeof for: What contexts can strict
typeof be used in that wouldn't already be covered with this definition of
auto? In particular, this already covers return types and local variables the
same way typeof would.
