[C++-sig] std::tr1::shared_ptr and C++ Singletons

[Piotr Jaroszynski]

Hello,

I have 2 problems:
1) class_<Foo, std::tr1::shared_ptr<Foo> > doesn't work=compile errors while 
boost::shared_ptr does. In the code I am writing bindings for 
std::tr1::shared_ptr is used.

2) I am not sure how to handle C++ Singletons. I thought that the proper way 
is to use return_value_policy<reference_existing_object>() for functions 
returning pointers to them as described in [1], but at the bottom of [2] Dave 
seems to disagree or I am missing something. Btw. how would you handle the 
situation when the get_it() is a method of object you want to get? I used:
def("get_it", &Foo::get_instance, 	
return_value_policy<reference_existing_object>());
Is it the best solution?
