Thanks for the document. Indeed, it seems that removing the requirement 
for a size() operator would make the CGAL Range concept would make it 
compatible (or as you pointed, turning it into a SizedRange concept).

Something already available and based on free functions (instead of 
methods, similarly to the "get" mechanism that we already use in CGAL) 
is the Boost Range: 
http://www.boost.org/doc/libs/1_39_0/libs/range/doc/boost_range.html
It seems to be even more generic (accepting also pairs of iterators 
–which would make the transition from pairs of iterators to range really 
straightfoward– and built-in arrays).
