 I am reluctant to merge any large patch that is not on my blocker list at
 this point in general, but I would greatly prefer if the lazy_attribute
 issue in this patch was fixed. The main reason is that otherwise some of
 the API in crystals will be different in 3.4.1 until the fix is merged and
 there is no clean way to handle this. I think since this is a combinat
 patch, i.e. no Cython, it is relatively low risk. But we are at the moment
 sitting around trying to get all blockers resolved and put out 3.4.1.rc2,
 so if the fix appears it should appear quickly.

 @Nicolas: I did not see the patch by Anne, but I will look it up.

 Cheers,

 Michael
