Re: [boost] An extension to boost::variant

boost::variant currently can not handle the following code: [...] boost::variant<foo*,foo&> v; [...] My question is essentially this: why couldn't it?

I suppose it requires the types to be value types, otherwise assignment and copy don't make sense. It's just like containers really. What's wrong with using T* or reference_wrapper<T> instead of T&?
