Hi,
I'm just wondering why , =, =, and are not supported by
collections.OrderedDict:
d1 = collections.OrderedDict(((a,1),(z,2),(k,3)))
d2 = d1.copy()
d2[z] = 4
d1 == d2
False
d1 d2

But why should the order be as if the OrderedDict was a list of tuples.
A dict can be considered as a mapping and then you might want to treat
either the key or the value as contravariant (the key I guess). So there

Or maybe not. If OrderedDicts are sequences as well as mappings, then we
should be able to sort them. And that seems a bit much even for me.
One thing that I've just noticed is that you can use , =, =, and
with sets:
