Comment(by nthiery):

 Peace. The lazy_attribute here is just a temporary workaround. Anne
 precisely did send an e-mail
 to the mailing list 2 days ago asking for confirmation for changing it
 systematically to a method
 in all the crystal library. This will come as a subsequent patch.

 Refactoring all the crap in the combinatorics code will take a while. No
 need to jump on every occasion to repeat the same arguments. We have heard
 them, and fully taken points for them.

 That being said, I still think that lazy attributes have their role to
 play in some well localized places in the user interface. I will run a
 complete discussion about this when time is ready for it. And the final
 code will follow whatever consensus emerges.
