I may not have time for review, but just one simple question: what are the advantages/disadvantages/differences in usage with stl_container<boost::variant>?
Hi, Here's another compelling reason why you'd use tuples: Try to implement Boost.Parameter or Boost.Bind or Boost.Lambda using std::vector<variant>. You can't! The types are unbounded. Variant can only deal with bounded types. From the variant docs: ''' A discriminated union container on some set of types is defined by instantiating the boost::variant class template with the desired types. These types are called *bounded types* ''' emphasis mine. But really, is this a review of tuples again? I think we are comparing apples and oranges again. tuples and variants are different tools for different tasks. Sure you can use a hammer to drive a screw, but I'd rather use a screwdriver.
