Thanks, Greg, I missed that.
More importantly, is there a good reason why we don't have d.pop() for
dictionaries?
My guess is because it's not generally useful to get an returns the value
arbitrary
value from a dict without its corresponding key. Hence the existence
of popitem().
However, d.pop(key, [default]) returns the value (or the default) and
consistency with other pops (a good thing in my view) would suggest that
d.pop() could return a random value, which would serve my purpose when
there is only one element.
