Well, unfortunately, I am back to square one. Again, I will not have
any problem if the views will be accessed from a left() and right()
functions but I can not find a way to get from the view data member to
the core that is not undefined in C++. For reference, I have to get
from the left data member to the bimap parent:

  class bimap { ... left_map_view left; ... } ;

Any attempt to use the offset of the member to get to the bimap class
seems to be forbidden by the standard.
So, I am back to using offset_ptr for the map_view data members and
maybe at one point think about migrating to function-accessed views to
avoid it :(
