Comment(by nasos_i@…):

 Hi Andrea,
 I just saw your post as I am getting ready to upload the new version of
 assignment operator.
 Anyway, you have some nice comments and as having worked on the subject I
 would like to add my experience:
 1. My first choice was to take a look at Boost::Assign. The basics of the
 ublas assignment code are inspired from Boost::Assign, but because of the
 relatively small (just 50 or 60) lines of code that were needed from Boost
 Assign, the rest should be considerably different (because of matrices and
 especially sparse containers).

 2. I am not sure whether it must be restricted to just rows (or columns).
 Anyway the code following allows for that behaviour if such verbosity is
 desired, based on Gunter's comments in the mailing list.
