Popping key causes dict derived from object to revert to object

Others have tried to explain and pointed out you can del and then use the
changed dict.

But consider the odd concept of writing your own trivial function.

def remaining(adict, anitem):
  _ = adict.pop(anitem)
  # alternatively duse del on dict and item
  return adict


>>> remaining({"first": 1, "second": 2, "third": 3}, "second")
{'first': 1, 'third': 3}


Or do you want to be able to call it as in dict.remaining(key) by
subclassing your own variant of dict and adding a similar method?
