I am not a native English speaker. But I totally do not support PEP 3131. If a program is written in English and commented by other language, I am read it. But if a program is written in other language, it will be full unreadable by me even it is commented by English. I think language is just a tool used for intercommunion. The best situation is all people use only one language.
