So, libraries could begin providing features that rely on decltype
even if the features won't be available on all compilers, so long as
the user has some way to conditionally include the features?

I'm wondering if/when Boost can offer a result_of implementation using
decltype along the lines of your suggested in N1454 (or typeof if
reference preservation is not necessary). Perhaps, Boost.TR1 could
provide a result_of that adheres to the current TR1 proposal and
Boost.Utility could provide a decltype-based result_of.

Also, I believe Boost.Typeof has library-based facilities for auto and
typeof but not decltype. Is there any chance of that happening on the
