Can anyone explain? > > I have used boost::function with sigc++, and my guess when it worked is that sigc++::slot (like boost slots and other similar libraries, including our own that we use for ardour) only requires an operator()() (i.e. functor invocation), which std::function also provides. last time i looked, sigc::slot is heavily templated, so any class that provides the required (minimal) API will work. what made you expect that it would *not* work?
