I would most strongly disagree. The reason is, of course, efficiency.
Ok, let it make more clear. If you want Boost to be ever stable library as Qt, GLib, STL you need this. This would allow to extend the class in future without breaking ABI.
I do not know of any implementation of the STL which is pimpl. With the exception of some parts of string and iostreams, they are also all header-only. pimpl is over-rated for not breaking the ABI. Chris
