Below is a first stab at documenting breaking changes for the release notes and/or result_of documentation.
Great, Daniel! Here are some comments to the release notes and general discussions. (My comments might be too detailed and not good for the release notes.) [Part 1 of 3]
BREAKING CHANGES TO BOOST RESULT_OF
[...] The macro BOOST_RESULT_OF_USE_DECLTYPE is defined when result_of is using decltype. Please see the result_of documentation for more information.
Better to mention BOOST_RESULT_OF_USE_TR1 to force TR1-style result_of?
1) TR1 protocol misusage [...] #ifdef BOOST_RESULT_OF_USE_DECLTYPE [...]
Should be !defined(BOOST_NO_DECLTYPE) && defined(BOOST_RESULT_OF_USE_DECLTYPE) One can define BOOST_RESULT_OF_USE_DECLTYPE on compilers without decltype support and, in that case, TR1-style result_of is used. This is the behavior of the macro. Once Eric changed this, but I claimed the regression and the change was reverted ( http://thread.gmane.org/gmane.comp.lib.boost.devel/230401/ ). In that thread, I might have over-emphasized the regression. If you think the effect of the code breakage is small enough, then I think it's OK to reapply Eric's change. Regards, Michel
