Re: [Boost-users] Off topic: Interface / design question

Appreciate your response. Any thoughts on why the designers of boost decided not to write interfaces for their classes?

I assume, you ask why boost does not generally provide functionality via polymorphic classes free of non-static data members? If so, the answer is rather simple: They follow the basic principle in the C++ world, that you should not pay for what you did not ask. It is always possible (for you!) to wrap any concrete class behind such an "interface", but it is not generally possible to obtain the maximum advantages of statically known classes, inlining, etc, if that what you get is a firewall interface.
