Comment (by wluebbe):
I do not think that it is //always// the right approach to solve the
easier problems before the hard ones.
We have done this with good reason for stage 1 (#15980). But the
completion of stage 1 has to precede the completion of stage 2. And now we
have the hard problems that remain in stage 1!
I think that stage 2 (#16052) could use a tool like
https://github.com/PythonCharmers/python-future to good effect.
Clearly this does not prevent us from solving some of the problems (added
originally to stage 2) in a stage 1 style (as was possible for
{{{filter}}} and {{{reduce}}}, and I think it is also possible for
{{{map}}} #16073!).
But we should try to complete stage 1 as soon as possible: if we cannot
solve those remaining hard problems then Sage will not available under
Python 3.
Anyway I will have a look at #16529 ;-)
And I will try to grok the //rich comparison// stuff - it is difficult and
but it is also necessary!
