FYI, alignas has a limitation in Preview that will affect any attempt to use it in aligned_storage. Specifically, classes with alignas'ed data members can't be passed by value.

Note that Preview's STL doesn't consistently support ref-qualifiers; I'm fixing this for RTM.

std::addressof() is in both 2013 and 2015 Preview. I recently found a minor issue, which I'm fixing for 2015 RTM - it didn't properly handle functions. For objects it worked fine in 2013.
