Hi Ralf,

yes, I have seen that. However, unfortunately that only tells me that a 
copy is to be expected there. It doesn't tell me how I can make a 
reference.

The reason for me creating a bpl::dict object is to be able to access 
the dict-specific methods (such as get()) which aren't available when I 
access the object. So, how can I cast to a derived type without a 
temporary ?

bpl::dict d = some_cast(o.attr("a_dict_member"));

??

Thanks,		Stefan
