No it isn't hard to use popitem() but it evidently proved hard for me to
remember that it was there.

Each collection class *is* a special case, and pop has to be ad

Thanks, Greg, I missed that.
More importantly, is there a good reason why
The pop() method exists for five mainstream data items and shows a range
of different behaviours for each of them.
But, of the five, pop for dictionaries is the only one for which the
first parameter is required and this makes d.pop() for dictionaries an
error rather than doing something usefu
You can do the following:
_,v = d.popitem()
Or:
key, value = d.popitem()

My guess is because it's not
