与收益相反？ [英] Opposite of yield?
问题描述
yield语句看起来是迈向python中某种轻量级并发编程的一大步。有没有
任何类似的好方法来做与收益相反的做法，只需坐在
（可能在循环中间）并等到其他一些例程
（等待模块不知道）投入一个值？
如果现在没有实现，那么它是否有可能在
要列出的事项清单？

The yield statement looks to be a big step toward some kind of
lightweight concurrency-oriented programming in python. Is there
any similarly nice way to do the opposite of yield, just sit around
(perhaps in the middle of a loop) and wait until some other routine
(unknown to the waiting module) hurls a value in?
If this is not implemented now, is there any chance that it''s on the
list of things to come?

机会不大。即使Stackless也不能再这样做了，如果我正确理解的话。
Not much chance. Even Stackless can''t do that any more, if I
understand correctly.

是的：
generator.next（）

对于休眠一段时间然后检查数据的线程来说，这听起来像是一个任务。
也让人想起（很久以前）有人提出了一个COME FROM声明
FORTRAN与GO TO相反。
也许是一个新的Python声明 ;吮吸？

Sounds like a task for a thread that sleeps a while then checks for the data.
Also reminiscent (a long time ago) someone proposed a COME FROM statement
for FORTRAN to be the inverse of GO TO.
Perhaps a new Python statement "suck"?
