I noticed that the following changes to result_of are not merged. They are old enough to be considered as "safe". 1. Bug fix for #5098 (decltype-based result_of cannot handle rvalues correctly) r68373 (12 months ago) https://svn.boost.org/trac/boost/changeset/68373 https://svn.boost.org/trac/boost/ticket/5098 2. Increasing BOOST_RESULT_OF_NUM_ARGS from 10 to 16 r71769 (9 months ago) https://svn.boost.org/trac/boost/changeset/71769 3. Documentation updates * r72336 (8 months ago) https://svn.boost.org/trac/boost/changeset/72336 * r72337 (8 months ago) https://svn.boost.org/trac/boost/changeset/72337 * r72377 (8 months ago) https://svn.boost.org/trac/boost/changeset/72377 Is it possible to merge them in this period? If OK, then I'll ping the maintainer. If not, I'll ping after the release branch for Boost 1.50 is open. Regards, Michel
