User-classes in types, current status of latest GIT bison branch..

[Byron Faber]

I happened upon a post on stackoverflow that referenced capacity in the
latest bison GIT code to list types as direct C++ classes rather then
pointers-to-classes in a union...  (e.g.
http://stackoverflow.com/questions/13053472/flex-and-bison-c-user-defined-class)

I was looking for that level of functionality for a project I'm working on
(with a release timeframe that's a year out at best..)

I only just started taking a look at the current code but was wondering
what the current status was?  'Is the intent really to ship with these
changes or is the code only included at the moment to scope-out such a
change?  What timeframe would one expect the current main code to make its
way into a release?

Thanks..
