I don't see to what your question applies. The proposal to introduce block-scope variables in Python relies on a special keyword to introduce them. So, any language with support for block-scoped vars would require "declaration", Python including.

They won't be common, if people don't find common need for them (they shouldn't). If they do... oh, people! > Paul -- Best regards, Paul mailto:pmis...@gmail.com _______________________________________________ Python-ideas mailing list -- python-ideas@python.org To unsubscribe send an email to python-ideas-le...@python.org https://mail.python.org/mailman3/lists/python-ideas.python.org/ Message archived at https://mail.python.org/archives/list/python-ideas@python.org/message/VHXFRQWQ7OE766S5AAD7J6NXVLJ5WS7T/ Code of Conduct: http://python.org/psf/codeofconduct/
