It would be nice if (as has been mentioned several times) any
deprecated code were removed for the 5.0 release, not before. Even
though (as has been discussed ad nauseam) we don't have the same "big"
number policy, there is a significant amount of stuff which could be
taken care of for that. That could also be when we remove the examples
directory, and quite a bit of other things that could be, like
iterators for combinatorial classes (has that reached the deadline
yet?), axes.py, the prec keyword (time? it would be a lot of work,
though) that shows up under
sage: search_src('deprecated')

Maybe, but that message is not so helpful. I guarantee you that you
don't need to know the history of Sage to do
sage: f=x^2
sage: f(2)
and expect 4. You just need to attend an insufficiently pedantic
algebra or calculus lecture :)
