[C++-sig] wrapped std::vector slice affecting items in a python list

[babak]

Hi,

I've come across some unusual behaviour that I was hoping some one might be
able to explain to me. 

In python I have a list and a wrapped std::vector<MyCustomType> (using the
vector_indexing_suite) where the list contains the items in the vector. If I
slice insert items into the vector then the items in the python list change.
The attached example illustrates this.

Is this behaviour expected ? 

I'm quite confused as to what's going on so any help clarifying this would
be greatly appreciated.
thanks,
Babak
