unpacking, so you can write:

That's very much like the classes built by namedtuple, but mutable.
I propose we add to the collections module another class factory. I am
calling it plainclass, but perhaps we can think of a better name. Here
is how it would be used:
>>> import collections
>>> Point = collections.plainclass('Point', 'x y')
The signature of the plainclass function would be exactly the same as
namedtuple, supporting the same alternative ways of naming the
There is an attempt to make such alternative: recordarray.
