Maybe there is no need to sacrifice performance, if a new, optional keyword
argument would be introduced to dict.items():
def items(self, named=False):
if named:
<yield namedtuples>
else:
<current behaviour>
Currently I need to define a namedtuple everywhere I do this and starmap the
dicts' items.
It'd be nice to have this option built-in or a new collections class like:
from collections import namedtuple
from itertools import starmap
DictItem = namedtuple('DictItem', ('key', 'value'))
class NamedDict(dict):
"""Dictionary that yields named tuples on item iterations."""
def items(self):
"""Yields DictItem named tuples."""
return starmap(DictItem, super().items())
