Category: function Group: None Status: Open Resolution: None Priority: 5 Submitted By: Douglas Gregor (dgregor) Assigned to: Douglas Gregor (dgregor) Summary: Const correctness violation Initial Comment: Boost.Function does not preserve const correctness for reference wrappers e.g. class function_object_type { public: void operator()() const {} }; void f() { const function_object_type const_function_object; boost::function<void()> function(boost::ref(const_function_object)); assert(function.target<function_object>() == &const_function_object); //const lost } I can see two possible solutions for this: add a flag: enum cv_qualifiers { const_ = 1, volatile_ = 1 << 1}; or don't unwrap references for target: function.target<boost::reference_wrapper<function_object> >() The first method seems preferable because it doesn't require the interface to change.
