finding the right = balance is some issue. I don't think it is something that can block Poi= nt class specifically.

= about Eigen, then:
1) I don't see any reason why not to borrow elements or classes fr= om Eigen (or any other library). I do believe though, that one should not b= ite more than it can chew.=C2=A0
standardization for one class is hard enough. standardiz= ing an entire library could takes years (even dozens of them), it is better= to start with something small and gradually increase the amount of classes= you add to the standard.
2) After digging a bit in the Eigen library, I couldn't fin= d an explicit Point class, are you sure they have implemented such class?= =C2=A0
