Re: [Boost-users] [any] bug? any_cast<>( any& ) returns by value

According to the documentation of boost::any_cast<T>, "if T is a reference to (possibly const qualified) ValueType, it [boost::any_cast] returns a reference to the held value."

Right. But this is still inconsistent both with variant's get<> and e.g. static_cast<>. The static_cast<> behaviour can't be done in current C++ (since you can't partially specialise function templates), so maybe variant's get<> should be changed? Hmm, maybe I lied when I said static_cast<> syntax is not possible... Lemme try. This should give static_cast<> semantics for any_cast (ie. <T> cast by value, by reference, and by pointer). Hmm, the attached stuff works, but how would const char* work in this setting...?
