Hi everyone,

I'm learning about the boost.geometry implementation by analyzing the
sources.

I have a question regarding the Ring model. How come it inherits from a
(STL) Sequence?
Inheriting from STL containers is said to be a problem because of the
lack of a virtual destructor.
However, this is only dangerous if you try to use dynamic polymorphism
with a container, accessing
the derived container member functions using a base class container, but
why would anyone use
pointers to containers?

Best regards,
Tomislav
