Fantastic. I've been working through some of the other new C++11 features
(auto, for-range and alias-declaration so far) and would love to see more
people working on this stuff.

As far as I'm aware, the late-specified return types feature is complete,
other than updating the external website. I fixed all the issues I could
find with it and added a bunch of tests as part of the 'auto' work. We're
already advertising support for it via __has_feature(cxx_trailing_return).
(One minor thing: we don't appear to have any tests checking that we
create the correct mangled names).
