I am not sure whether GCC-XML reports friendship or not. Py++ do take into
account free operators. It injects them directly into the class. Take a look on
creator_t._adopt_free_operator method.
For next release I plan to add "add_method" to the decl_wrappers.class_t.
And an algorithm that will find all functions, that could be exposed as methods.
For example:
struct data{
X x;
Y y;
};
std::auto_ptr< data > create();
could be added as "init" method
void initialize( data& )
could be added as new method
User will be able to write in Python:
d = data();
d.initialize()
This feature + FT will make Py++ to handle C code much better than now.
