[Python-ideas] namedtuple for dict.items()/collections.abc.Mappings.items()

I have a lot of code that looks like this:     def filter(self, it, defs):         for x in it:             for y in _match_helper(self.key, defs, x[0]):                 yield (y, x[1])     def filter(self, it):         for el in it:             try:                 if self.compiled.search(el[0]):                     yield el                 elif not self.skippable:                     raise ValidationError             except TypeError:                 if not self.skippable:                     raise ValidationError     def filter(self, it, ty):         for el in it:             # this may TypeError if ty is not a type nor a tuple of types             # but that's actually the programmer's error             if isinstance(el[1], ty):                 yield el             elif not self.skippable:                 # and this one is for actual validation                 raise ValidationError It'd be quite nice if dict.items() returned a namedtuple so all these x[0], x[1], el[0], el[1], etc would instead be x.key, x.value, el.key, el.value, etc. It would be more readable and more maintainable.
