I was trying to write this documentation when I noticed that the docs already
mention this! "The stmt and setup parameters can

Hi, I first want to thank everyone in the community for the contributions

Thank you, Geoffrey, for pointing this out. I'd have done better to
prefixed the title with OFF-TOPIC. That would have been more polite.
To answer your question: Django created a new community of Python
users.
One important difference between MappingProxyType and a "proper"
frozendict, as analog to frozenset, is that MappingProxyType doesn't have
any method to return mutated versions of itself.

In tri.struct we have a class Frozen

better in the standard library, especially now with data classes! If we had

MappingProxyType.copy()?
Hi everyone and good morning to some of you,
Since asyncio and the async/await syntax are both part of Python, I think
that we should extend TestCase to support it. The simplest solution that
I can think of is to create unittest.AsyncTestCase sub-class with the
following extensions:
- create a
How does a frozendict help in that example? It's not obvious to me.
Despite not understanding that example, I'm +1 for having a frozendict. I
don't think it'll increase cognitive load much, as it'll sit right next to
frozenset when someone reads the builtins in alphabetical order. In my own

I'm not for the rename, myself. Though I'd not be against a frozendict
factory in builtins, a tiny shim for MappingProxyType.
It would help over using a regular dict as a default argument to a function
by preventing accidental mutation of the default or constant mapping. This
is a quickly contrived example of the convert_price function now having a
side effect by changing the translation_map.

Steven, that's a great idea, and I would be 100% up for your suggestion to
have types.MappingProxyType renamed to frozendict. However, the differences
in the behavior of MappingProxyType's constructor versus dict's would make
the API's behavior confusing IMO. For example, MappingProxyType(x=5,

That's a good suggestion. Ultimately, if there are not enough various use
cases for a frozendict class, I think we could add something like this as
an example recipe similar to the recipe section in itertools. I would be
hesitant to add a quick shim to the standard library as I can't

That is interesting. From my recollection, when OrderedDict was
reimplemented in C, there was advice on the thread to not implement it as a
subclass of dict.

I'm far from the right person to comment on the exact reasons, but perhaps
