Hi,Nope.
Ok, great.To be honest, I was more focused on forward_list and treated compressed_pair more as a place holder albeit one that did what it needs to do. I studied some other implementations and put something together. I tested the sizeof and it did the trick.
I did think the single argument ctors were unnatural. I couldn't see myself using them because of the ambiguities just mentioned and, well, it's a *pair* after all. I'm working on a version where I remove all single argument ctors.
I also removed the ifdef. I'm going with the dummy member for reasons
outlined in the comment.
Also. I'm using some C++-09 features. It was convenient. If this is
really going to get used in other containers it might be good to roll
back to C++-03 features. That way, the other containers will used
compressed pair allocators before C++-09 becomes default. I think we
have internal replacements for remove_cv and such.
Uhhmm, I didn't consider that issue. In fact, as an independently useful extension, it would be nice if it could work also in C++03 mode. All in all, I'm thinking we should probably change a bit our plans, if you agree: let's separate the two projects, the main one being forward_list. I would ask you to contribute first a self-contained forward_list, using tuple for the pair of allocators. That could go in almost immediately. I still believe a __compressed_pair makes sense as an extension, but we should probably perfect it separately, and do our best to avoid relying on C++03 features for it (TR1 is fine). What do you think? Is it too much work for you to quickly split out a self-contained forward_list using std::tuple?
Paolo.
