Hello,
Python 3.10 comes with the built-in *anext()* but I think we may be missing
some other equivalent built-in functions like *list* and *enumerate*.
I didn't discuss the idea of creating a PEP for this but I would like to
get some help with the implementation.
The equivalent Python code would

Tomorrow is the scheduled release of Python 3.10 beta 2 but unfortunately
we have several release blockers:

To the contrary, I think if you want the CI jobs to be faster you should
add the CFLAGS to the configure call used to run the CI jobs.

--with-pydebug default compiler flags is a trade-off between "runtime
checks for debug" and performance. -O0 makes Python slower. For
example, we want to Python CI to run as fast as possible.
I don't want to fight for https://bugs.python.org/issue38350 I simply
learnt to type: ./configure --with-p

I am sorry to have missed your previous e-mail with a
When you're installing Visual Studio the C++ tools version is listed
under the selected components as "v14x".
However, at this stage, the *only* version in circulation is 14.x - mine
shows v142. Until the 14 changes to a "15", it will be binary compatible
and so you can use any version at all
I'm confused. I've always assumed that --with-pydebug was intended for the
situation where you're modifying the C code, so obviously you might have to
debug C code. (I know that was the case when we introduced it, decades
ago.) If that's not the goal, then what is --py-debug used for?
On Mon, May
How do you check that the C++ tools are v14.x?

Yea, that's up in

"Debugging" means many things. Python is built with -Og because it
makes Python faster than -O0, and most developers debug Python code,
not C code (in gdb).
If you don't need to go up to the gdb/lldb level, -Og is fine.
It would even make sense to build Python with -O3 in debug mode if you
don't
