[Boost-users] for_each on container of any

Hello!

I like the idea of containers (e.g. std::vector) of boost::any.
But I'd like to execute some operation on each item of the
sequence. Unfortenuately I would need to know the set of types in
the container and check every one of them if I was going to use
the std::for_each with a void(*)(boost::any&). That's not good at
all. I'd like to pass a function object like:

struct MyOperation
{
   template<typename T>
   void operator() (T&) const;
};

How can I do so? Is there any algorithm for doing so provided by
boost?
