We don't even have an official implementation yet, and you already want
to start prescribing coding style? We probably have months before 3.8
alpha comes out.
This is an excellent way to look at the picture with a user's eyes. You
immediately see what parts of the design lend themselves well to
practice and what don't, which details are unclear, which additional
features are missing (note how he revealed the lack of tuple unpacking)
-- by all means, something to do at the design stage, before doing the
implementation.
It's also a testimony of how much an improvement a feature will _really_
be -- something that contrived examples can't tell.
I salute Victor for such an enlightemed idea and going for the trouble
to carry it out!
I appreciate your enthusiasm, but what's the rush? Give people a chance
to play with the syntax in the REPL before making Thou Shalt and Thou
Shalt Not rules for coding style and making wholesale changes to the std
lib.
This topic has been argued and argued and argued on two mailing lists
for over four months. Let's take a couple of weeks to catch our breath,
wait for the implementation to actually hit the 3.8 repo, before trying
to prescribe coding style or thinking about which parts of the std lib
should be refactored to use it and which shouldn't.
There is no need to rush into making changes. Let them happen naturally.
