Incompatible change discussion: Pretty printing of ordered dict.

Hi all,

As you may or may not be aware, with Python 3.6 the dictionary are
ordered by default. It is technically an implementation detail, though
some people would love for it not to.

Regardless, IPython has for a long time pretty-printed the dictionary
with _sorted_ keys, this thus prevent to teach python and show that
dictionaries maintain order. Thus there is the question of wether we
should disable sorting keys while pretty-printing.

This seem like a minor change, but I'd like to know if some of you are
_relying_ on the ordering of dict when they are printed, or have
compelling arguments against (or for) removing sorting of the keys
before pretty_printing.

If you care about the above subject, please have your voice heard in
above issue.

Thanks,
