Hi everyone,
The formal review of Joaquín M. López Muñoz's PolyCollection library 
starts today.
[...]
* boost::function_collection
I could not understand from the documentation what it is I am supposed 
to be
inserting into a function_collection. The tutorial did not explain 
this to me and the
reference's technical explanation on this eluded me.
You can insert into a boost::function_collection<Signature> any entity 
that a
std::function<Signature> object could be constructed from. For instance,
boost::function_collection holds callable entities that can 
be invoked with
a (convertible to) int argument and return a (convertible to) double result:

   double f(int n){return (double)n;}

   struct g
   {
     double operator()(int n)const{return (double)2*n;}
   };

   boost::function_collection c;
   c.insert(&f);
   c.insert(g{});
   double factor=3;
   c.insert([=](int n){return factor*n;});

   for(const auto& x:c)std::cout<http://tinyurl.com/kddv9nz . Didn't you find this 
section
sufficiently explanatory?
