No. I need iteration in python over exported c++ collection not to cause
exception to be generated in C++:

mymodule.cpp
    class_<std::vector<Foo>, boost::noncopyable >( "FooArray" )
        ....
        .def( vector_indexing_suite<std::vector<Foo> >() )
        ;

test.py:

def test_foo():
   arr = mymodule.FooArray( 5 )
   for e in arr: 
       pass

This code causes an exception being thrown to stop iteration. I just wonder if
there is means to avoid it.
