Question: I'm currently going to write big project in c++11.

I'm searching for some time good c++11/c++ reflection library and I've found several different libraries, but most of them are simply not updated for last couple of years or their functionality is very limited.

Could you tell me if there is a really good library for c++1/c++ for reflection? (I want to have static and dynamic reflection, know as much information as I can about methods, classes etc, can dynamically add and access methods etc.)

Or maybe c++11 has provided some additional functionality that will help to better design reflection libraries and should I write it by myself? (I haven't found information about it though.)

Answer: 
It seems that there is a library that satisifies your "broad" requirements. Take a look at Mirror: [Boost.Mirror](https://svn.boost.org/trac/boost/wiki/LibrariesUnderConstruction#Boost.Mirror). Note that it is officially NOT part of boost. You also could take a look at other libraries: [Reflective Programming](https://svn.boost.org/trac/boost/wiki/LibrariesUnderConstruction#ReflectiveProgramming).
QT has a primitive form of reflection, you probably want to take a loot at it.
