Hmmmm. now that I think about it, it is also possible to change the implementation of pop_back to make it so that it would not need to use 'prior'. The end iterator can be abstracted such that it compares equal to i through next(i). I'll see if that works out.
Yep. It works like a charm. I have a fix. Now this works:
{ list<int, int> l(1, 2); std::cout << pop_back(l) << std::endl; BOOST_TEST((pop_back(l) == make_list(1))); }
Now, indeed, the docs works as advertized.
Thanks for your nudging, Eric. I truly appreciate it. You get my neurons humming. Committed to trunk. I'd welcome a quick review before I make this official.
Very clever! Looks good to me.
Cool. Now I notice that pop_back_iterator is the workings of a reusable iterator_adapter. Regards, -- Joel de Guzman http://www.boostpro.com http://boost-spirit.com
