Alexandre Vassalotti <alexan...@peadrop.com> added the comment: Here is a patch to backport dict and set comprehensions to the trunk.
The patch preserves the Python 3.x's syntax and semantics of the feature. Although this makes dict and set comprehensions is inconsistent with list comprehension, I believe this is reasonable since the backport aimed to improve the compatibility of Python 2.x with Python 3.x. The patch also adds support for dict and set comprehensions to the 'compiler' package. However, the support is quirky and use the list comprehension semantics of Python 2.x. This allowed me to keep the patch simple and to keep myself sane ;-). Finally, the patch changes the name of the following syntax nodes: 'gen_expr', 'gen_iter', 'gen_if', and 'testlist_gexp'. I don't know if we have compatibility requirements for this; so I don't know if this is an issue. ---------- keywords: +patch nosy: +alexandre.vassalotti stage: -> patch review title: Backport dict comprehensions -> Backport set and dict comprehensions Added file: http://bugs.python.org/file14661/backport_dict_and_set_comprehension.diff _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue2333> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
