[pygccxml-development] How to get the class_t from a typedef_t

[Gustavo C. <gjc...@gm...>]

I am trying to parse C++ code like:

template<typename R,
   typename T1 = empty, typename T2 = empty,
   typename T3 = empty, typename T4 = empty,
   typename T5 = empty, typename T6 = empty>
class Callback ...;

later:

template<typename T1 = empty, typename T2 = empty,
         typename T3 = empty, typename T4 = empty>
class CallbackTraceSource : public CallbackTraceSourceBase {
public:

  typedef Callback<void,TraceContext const &,T1,T2,T3,T4> CallbackType;

...
};

I am trying to navigate from the CallbackTraceSource class, but no matter
what I do I cannot make pygccxml give me the class_t corresponding to the
typedef_t named 'CallbackType'.  I can only get a declarated_t or
class_declaration_t, but I cannot find any way to get the corresponding
class_t.  What am I missing?  I really need to do this, because I have to
work around the "template arguments being treated as strings, not types"
problem I mentioned a while ago.
