Re: [Boost-users] BOOST_RESULT_OF_USE_DECLTYPE not default on C++11 compilers

Jeremiah Willcock writes:

At least on GCC 4.6 in C++0x (C++11) mode, BOOST_RESULT_OF_USE_DECLTYPE is not set by default, preventing classes such as boost::transform_iterator from working on built-in lambda expressions. Is there a reason that the use of decltype is not on by default for compilers that support it, perhaps with a flag to force emulation mode (like Boost.Move supports)?

I noticed the same. Although gcc's decltype has been partially broken, at least on gcc, and can sometimes have strange effects when used with `result_of`. (I think this actually used to be a bug in the draft.) This situation would have to be resolved in Boost.Config or with a `result_of` specific solution. -- Philipp Moeller
