Hi there, Before we have this discussion yet again, I will record the official stance in the zope toolkit decisions document, and I'll quote it here: * When code moves to a new location to import it from (in the same or another package), use a ``from foo import bar`` statement, with a ``#BBB`` comment to indicate the import is only there to support backwards compatibility. In the CHANGES.txt of a package, state that an import location got deprecated and where the new location is (making this a feature release, not a bugfix release). Reasons: * it avoid a dependency on zope.deprecation, which is quite involved in its implementation, using proxies. * A ``from .. import ..`` is immediately comprehensible to any Python programmer as well as tools. * Deprecation warnings make it hard to write a library that supports multiple versions of another library; a change in an indirect dependency can create deprecation warnings that the original developer does not care about. * We are in the process of developing a testrunner extension that will report on indirect imports, and a ZODB upgrade procedure. Feel free to discuss it, either to add arguments to refine this, or to attempt to overthrow this decision entirely. Regards, Martijn
