Some Questions:<br>This Indexing Suite 2: What is it and how do I use that instead of the normal indexing suite? even better error msgs will help.<br>The pickle protocol method looks like too much work, given that some of these objects have dozens of data members that need to be copied. Implementing an explicit __deepcopy__ for every class could be a lot of work , and I do not understand what that memo argument is doing.<br>
I had hoped that BP would just know what to do. After all, all the classes in question have perfectly good copy ctors. I take it that 'class_<...>.enable_copy()' and the other ideas in that thread were never implemented? <br>
