I am trying to use a class template for each data-

boost::any has already been recommended, however it's for anything, so you can't expect much from it.

If you know the various types ahead of time, you're better using boost::variant.

typedef boost::variant variant_type;

struct Print: boost::static_visitor<>
{
  void operator()(Foo const& f) const { f.print(std::cout); }

  template 
  void operator()(T const& t) const { std::cout << t << '\n'; }
};

void func(variant_type const& v) // not template
{
  boost::apply_visitor(Print(), v); // compile-time checking
                                    // that all types are handled
}
