std::function<> is a lot more than syntactic sugar, it is a 
runtime-heavy construct. From 
http://en.cppreference.com/w/cpp/utility/functional/function :

«Class template std::function is a general-purpose polymorphic 
function wrapper. Instances of std::function can store, copy, and 
invoke any Callable target -- functions, lambda expressions, bind 
expressions, or other function objects, as well as pointers to 
member functions and pointers to data members.»

I don't think you want this...
