If the compiler can do some type inference, it can optimize out those multiple calls pretty straightforwardly.
It can be tipped like that:
di = dict(int) di.setdefault(0) di[key] += 1
dl = dict(list)
dl.setdefault([])
dl.append("word")
dl.extend(mylist)But the point is that if method not found in dict it delegated to container type specified in constructor.
It solves dict specialization without bloating dict class and is generic.
