Re: [boost] Please look at my suggested pimpl library in the filevault.

The trouble is pimpl's are normally idioms not libraries (because you have to write all the forwarding functions by hand). If I understand what you're doing here correctly, your pimple class is really just another smart pointer, but with deep copy semantics.

These smart_ptr/policy_ptr variations appear all the time. I've decided to just ignore them. People should be able to find PBSP themselves and know that it's all just another policy. Gennadiy
