The boost shared_ptr has a different implementation and some extensions
that the tr1 shared_ptr doesn't have. Like make_shared for instance.
I have code that uses a lot of boost::shared_ptr and there are some
things that are just broken in vc9's tr1 implementation. You can't store
tr1 functions in a std::container for instance because of a bug. I would
really like to get the no copy no throw container manipulation for
things like boost::function and boost::shared_ptr and all it takes is a
simple trait specialization.
I could do these myself in a precompiled header or something but they
seem like optimizations that are so trivial and useful that they should
go into boost so everyone can benefit from them.
Thanks,
