I am -1 on sorting the output of dominant_maximal_weights. That seems to have a fixed output order (assuming RecursivelyEnumeratedSet does, but it should). I think it would be better for the printing to match that order. Or does the output order change in Python3?

So that means anything involving RecursivelyEnumeratedSet will likely be inconsistent across Python versions. :/ Hmmm... I don't really like the sorting on the print output that splits it from the dominant_maximal_weights() output, but IMO that should not be sorted either. We definitely do not want to mark the output as # random. I guess we do # py2 and # py3 versions? The only other decent option would be to always sort the output of dominant_maximal_weights().

In ​https://trac.sagemath.org/ticket/27710, following the discussion in ​https://groups.google.com/forum/#!topic/sage-devel/kokSk7Nc8T8 I've marked some output as #random print output.

Is it a response to Travis or do you mean with this ticket ? Because the order of results you show are exactly what i get without this ticket.

Ok i will do that.

This works for me. I'm not delighted with more # py2 and # py3 doctests, but maybe that's the best solution here. Anyone object to a positive review?
