Randy Abernethy commented on THRIFT-2717:
-----------------------------------------

Facebook used "cpp2". This avoids + anywhere in the text (which I think is a 
very good idea!) and makes it clear that this is the second cpp version. This 
is similar to the problem with Python 2/3. They are not fully compatible and 
some folks want one while others want the other. If we need to support two 
versions having a cpp and a cpp2 is not too crazy. Whatever the case the /lib 
dir and the compiler switch should be the same.

> instead of adding another set of options to 'old' cpp generator I've started 
> creating new one in:
> https://github.com/hcorg/thrift/tree/cpp11_generator
> using old as an reference
> main goals:
>  * code compatible with old librart (at least for first tests, new lib and 
> compiler switches can be added later)
>  * no more ugly {{__isset}} structure -> boost::optional for optional values
>  * as a result - no more {{__}} in names, which violates C++ standard
>  * all generation code will have own unit tests (TDD used wherever possible)
>  * generated types headers independent from Thrift header, to allow other 
> layers of application using generated types without dependency leaks
>  * each type will generate own header/cpp file - easier for user to include 
> only used parts.
>  * unordered map/sets
>  * returning using move semantics, no more ugly 'return via output parameter' 
> (still possible as option thou - sometimes it's needed for performance)
>  * async client using boost::future
>  * enum classes
>  * initializer lists for constants (maybe)
> I'm aiming in C++11 subset available in gcc 4.8 and MSVC 2013
> currently I have only complete enum generation, but work is in progress
> all comments etc are very welcome :)
