Re: [boost] 30%?

Personally, as a Boost user I would rather have these speed increase
rather than a clean implementation as having shared_ptr etc I don't neeed
to develop my own, so I don'y need a clean reference implementation. I see
Boost as being a set of very useful extensions to the standard library and
would expect stl implementation to be as fast as possible, even at the
expense of readability, as you can never know where your classes could be
used.

Cheers,

Ben
