[Python-ideas] The AttributeError/__getattr__ mechanism

[王珺]

Hello everyone:

I'm suggesting a modification to the AttributeError/__getattr__ mechanism,
see issue25634:
http://bugs.python.org/issue25634

I used __getattr__ sometimes, and descriptor especially property is so
widely used. I wonder whether someone had encountered the same problem with
me.

However, this is a complicated problem including performance issues, and
backward compatibility.

Thanks for your attention,
Jun Wang
