[性能相关]PEP draft： Hide implementation details in the C API
janxin · Jul 11, 2017 via iPhone · 2141 viewsThis topic created in 3213 days ago, the information mentioned may be changed or developed.
虽然只是开始阶段，但是起码描绘的场景还是不错的。不过就看保守的 py 社区怎么看了。
Modify the C API to remove implementation details. Add an opt-in option
to compile C extensions to get the old full API with implementation
details.
The modified C API allows to more easily experiment new optimizations:
* Indirect Reference Counting
* Remove Reference Counting, New Garbage Collector
* Remove the GIL
* Tagged pointers
Reference counting may be emulated in a future implementation for
backward compatibility.

python 在走 perl 的老路，两个字，药丸。

楼上说 python 药丸的，应该是不熟悉机器学习领域

楼上小学生太狂妄了，我就是痛心 python 目前只能龟缩在 ML/AI 领域显摆，才喷它在走 perl 的路子的。
v2 的小学生真是缺乏教育。 |

各个语言都有他的应用领域，Python 也是一样，我认为差异化才是目前语言的趋势。
C/C++，Java，PHP 都有自己的一边天，Python 也有，也没必要去抢占别人的领地。 |

不过 CPython 性能问题确实需要更好解决。

是个好兆头，cpython 实在是比较烂..
