objgenerator: Implement return with value and .close() method. Return with value gets converted to StopIteration(value). Implementation keeps optimizing against creating of possibly unneeded exception objects, so there're considerable refactoring to implement these features. 2014-03-23 19:48:29 +00:00			`def gen():`

tests: Modify tests that print repr of an exception with 1 arg. In Python 3.7 the behaviour of repr() of an exception with one argument changed: it no longer prints a trailing comma in the argument list. See https://bugs.python.org/issue30399 This patch modifies tests that rely on this behaviour to not rely on it. And the python34.py test is updated to include a test for this behaviour with a .exp file. 2018-08-17 05:46:04 +00:00			`print(type(e), e.args)`
py/objgenerator: Remove TODO about returning gen being called again. The code implements correct behaviour, as tested by the new test case added in this commit. 2018-09-27 05:18:24 +00:00
