The same use case as for all dead code: it could be a placeholder for something better in the future. It could also be generated code where the generator expects the optimizer to remove it (or doesn't care). If you want to do linter integration that should probably be integrated with the user's editor, like it is in PyCharm, and IIUC people can do this in e.g. Emacs, Sublime or Vim as well.

I haven't seen this warning yet. I take it this is new in the 3.6 branch? -- --Guido van Rossum (python.org/~guido) _______________________________________________ Python-Dev mailing list Python-Dev@python.org https://mail.python.org/mailman/listinfo/python-dev Unsubscribe: https://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
