pep3104 Access to Names in Outer Scopes pep3105 Make print a function pep3111 Simple input built-in in Python 3000 pep3113 Removal of Tuple Parameter Unpacking pep3114 Renaming iterator.next() to .__next__() pep3115 Metaclasses in Python 3000 pep3127 Integer Literal Support and Syntax pep3129 Class Decorators pep3132 Extended Iterable Unpacking had to backport __build_class__ in bltinmodule.c to get metaclasses working. u can go to http://www-rcf.usc.edu/~kaizhu/work/py3to2/ for more info install/usage summary: 1. build python 2.5.2 w/ patched ceval.c & bltinmodule.c 2. download scripts: py3to2.py & _py3to2.py 3. ln -s python3.0 python3k 4. run python2.5 & type 'import py3to2' # it will automatically run the pep tests the script provides 3 functions similar to those in __builtin__: compile_py3k, exec_py3k, eval_py3k right now, working on backporting pep 3102 & 3107 - annotations & keyword-only arguments. apparently appending the co_kwonlyargcount attr to codeobject in 2.5.2 doesn't seem to affect the build _______________________________________ Python tracker <[EMAIL PROTECTED]> <http://bugs.python.org/issue3238> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
