New submission from Simon Weber:
When dealing with implicit relative imports of the form "import
<dotted_as_names> as...", the 2to3 import fixer will rewrite them as "from .
import <dotted_as_names> as...".
This is invalid syntax. Here's an example:
$ tree package/
package/
├── __init__.py
├── rootmod.py
└── subpackage
├── __init__.py
└── mod.py
1 directory, 4 files
$ cat package/rootmod.py # this is the only nonempty file
import subpackage.mod as my_name
$ python package/rootmod.py
$ 2to3 -w -f import package/

-import subpackage.mod as my_name

$ python package/rootmod.py
File "package/rootmod.py", line 1
from . import subpackage.mod as my_name
^
SyntaxError: invalid syntax
Probably the easiest way to rewrite this is "from .subpackage import mod as
my_name".
