Raymond Hettinger added the comment: +1 for the proposed change. It should add there is also an enforced (and obvious) restriction that the variable not have been declared nonlocal. -- nosy: +rhettinger ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue14544 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue14544] Limit global keyword name conflicts in language spec to those enforced by CPython
New submission from Nick Coghlan ncogh...@gmail.com: The language spec currently includes the following paragraph [1]: Names listed in a global statement must not be defined as formal parameters or in a for loop control target, class definition, function definition, or import statement. While the first restriction is real (and enforced by CPython), since formal parameters are explicitly defined as local variables, there's no obvious rationale for the last 4 restrictions (and CPython doesn't enforce any of them). The proposal is that the paragraph be simplified to: Names listed in a global statement must not also be defined as formal function parameters. Attempting to do so raises SyntaxError. The current (incorrect!) CPython implementation detail note will be removed. A similar clarification will also be made in the nonlocal statement documentation.

Alex Gaynor alex.gay...@gmail.com added the comment: This shouldn't be a problem for PyPy, in fact I'm almost positive that we implement this already (since Django has a test that uses this feature). If/when the spec is changed please make sure there are tests for all these cases so we *know* it works though. -- nosy: +alex ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue14544 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
