Comment (by spillner@…):

 I know that there's some decltype support in 11.1, but I received number
 of compilation warnings (specifically on things like

 template < class T > struct Z {
   T dummy;
   typedef decltype(dummy.get()) retval;
 };

 ) that went away when shifting to ICC 12 or GCC, so I enabled that only in
 12 and up.  This seems consistent with http://software.intel.com/en-

 us/articles/c0x-features-supported-by-intel-c-compiler/ , which is more
 conservative than e.g.
 http://wiki.apache.org/stdcxx/C%2B%2B0xCompilerSupport .

 I didn't have a mature use case for the other features, so I confined my
 attention to the three in the patch.  They're also all supported by GCC,
 which gave me greater confidence in testing.  Bottom line, I don't have
 any reason to believe that the features you named don't work well, I just
 haven't proven that they do.
