Description
Currently the guidelines only mention this in the unclassified proto-rules section.
And speaking of std::bind, Stephen T. Lavavej criticizes it so much I’m starting to wonder if it is indeed going to fade away in future. Should lambdas be recommended instead?
But Herb Sutter[1] and Scott Meyers[2] agree std::bind should be avoided, so perhaps a rule on the matter is in order.
