And if you prefer to read the mailing list with an NNTP client, you
can point your favorite newsreader at news.gmane.org and subscribe to

I am not sure about what are you saying.
Does it really solve the usage of dict views?
How about my example? (`assert d.keys() == {"spam", "egg"}`)

Oh, ! am talking about dict views.  I meant there is no difference
between "how dict view is useful for dict" and "how dict view is
useful for frozendict".

But I am still not sure about the optimizations and functional
programming you are talking about.
Please elaborate more, please?
