Change the PEP to add that __exit__() must re-raise the exception
...
passed in, if any. This appears to be a deviation from how the PEP
was originally seen; but I think it's essential to be able to make a
simple promise about generators decorated with @contextmanager.
Added the transition plan and the __future__ statement.
Also some miscellaneous cleanup.
2006-02-28 20:58:17 +00:00

Change the translation slightly.
...
ctx.__exit__ is now bound before ctx.__enter__;
ctx.__enter__ is still called before the try-block
is entered, but VAR is assigned *inside* the try-block.
Clarify what happens to break, continue, return.
