Hello I have some trouble with handling c++-container.

I have these code:

typedef struct foo {
   typedef std::vector<double> pt_coords;
   typedef std::vector<pt_coords> pt_list;
};

foo return_foo();

Now I want to wrap these, but I don't know how! I have test this, but I think it's wrong:

BOOST_PYTHON_MODULE(...) {
   implicitly_convertible<foo::pt_coords,tuple>();

implicitly_convertible<foo::pt_list,list>();
}

By using this in Python I get:

TypeError: No Python class registered for C++ class std::vector<std::vector<double, std::allocator<double> >, std::allocator<std::vector<double, std::allocator<double> > > >

How to do this right?

Greetings
