Ultimate++ 511 was released. U++ is a C++ cross-platform rapid application development suite, where "rapid" is achieved by the 'smart and aggresive' use of C++ features. The main improvement of the new version is the
Assist++ (code completion, browsing and transformation tool) in TheIDE. See an
overview of the library.

Hardly. Value is just a type-safe wrapper on top of void*.
No, you can't. Void* is just a way to pass around objects of unknown type. Dynamic typing is a whole lot more. In particular, dynamic typing requires some form of generic dispatch. Value is just a way to box up an object and pass it around. You still need to unbox it to use it.
Mental overhead is quite low, but I can agree that learning curve is more steep (but much less steep than the one for STL/Boost combo).
For a C++ programmer, maybe. For anybody who is used to actual productive languages, no it's not. Passing around objects in Lisp has almost no semantics. Everything is a reference. In C++, you have three sets of semantics (reference, value, pointer), and U++ adds another set of its own.
As for callbacks, 1:1 comparison is stupid there. C++ has different set of features and different ways of dealing with things.
The claim was that callbacks subsume the uses of closures. Closures do way more than callbacks, and there is no good replacement for them in C++.
