<br>
As you may or may not be aware, with Python 3.6 the dictionary are<br>
ordered by default. It is technically an implementation detail, though<br>
some people would love for it not to.<br>
<br>
Regardless, IPython has for a long time pretty-printed the dictionary<br>
with _sorted_ keys, this thus prevent to teach python and show that<br>
dictionaries maintain order. Thus there is the question of wether we<br>
should disable sorting keys while pretty-printing.<br>

<br>
This seem like a minor change, but I'd like to know if some of you are<br>
_relying_ on the ordering of dict when they are printed, or have<br>
compelling arguments against (or for) removing sorting of the keys<br>
before pretty_printing.<br>
<br>
If you care about the above subject, please have your voice heard in<br>
above issue.<br>
<br>
Thanks,<br>
