Re: [Python-ideas] Add recordlcass to collections module
It would need to be a list of the members are mutable. As to the other questions, yes, do we need another module in the standard library?Angus

Wouldn't need a new module. This would be a perfect fit for the existing collections module where namedtuple already resides. I Googled "pypi namedlist", and the top three results were all other implementations of named lists or something similar: - namedlist <https://pypi.org/project/namedlist/>, which I have personally used and found extremely useful - list-property <https://pypi.org/project/list-property/> - mutabletuple <https://pypi.org/project/mutabletuple/> Clearly the concept is useful enough to have several competing implementations on PyPI, and to me that is a point in favor of picking an implementation and adding it to the stdlib as the one obvious way to do it. So +1 from me.

A named list would allow sequence operations such as iteration. Dataclasses, IIUC, do not support sequence operations.
