Hi all,
Regarding the behaviour of the "async with" statement: it seems that the
description of it in PEP492, and the language documentation, do not match
the behaviour of CPython (v3.6.1).
The PEP and the docs here:
Hi Yury,
That's great news about the speed improvements with the dict offset cache!

Ok, so

I've tried a small number of those benchmarks, but not in any rigorous
way, and not
Hi Yuri,
I think these are great ideas to speed up CPython. They are probably
the simplest yet most effective ways to get performance improvements
in the VM.
MicroPython has had LOAD_METHOD/CALL_METHOD from the start (inspired
by PyPy, and the main reason to have it is because you don't need to

I never did such fine grained analysis with MicroPython.
Hi python-dev,
We have a Python script that runs correctly under Python 2.6, 2.7 and 3.3+.
It is executed on a *nix system using the "python" executable (ie not
python2 or python3 specifically). This works just fine for systems that
have Python 2 installed, or 2 and 3, or just 3 and symlink
Hi Yury,
In your PEP 492 draft, in the Grammar section, I think you're missing
the modifications to the flow_stmt line.
Cheers,
Damien.
