I'm having a problem with Boost.Tuple virtual functions. Consider the code below, I would have expected the output to be "B::foo()" but instead get "A::foo()". Am I missing something here?
Yes, if you copy a A&, you end up with an A. This is known as 'slicing', and can be a pain. It has nothing to do with boost, or tuple.
Indeed. Derive A from boost::noncopyable to catch this mistake. Olaf
