This happens if you do ``import string`` from within a package and there is no 'string' module there. This leads to sys.modules['pkg.string'] being None and thus redirecting to sys.modules['string']. This is only useful for classic relative import semantics and thus can probably go once absolute imports are the only way to do imports. -Brett -------------- next part -------------- An HTML attachment was scrubbed...
