I don’t understand what the bug is. |

If import from __future__ is written in multiple lines, then a parser internally used by 2to3 recognizes only the first line. (However Python interpreter properly supports multi-line imports from __future__.) test1.py contains multi-line import from __future__. test2.py contains single-line import from __future__. 2to3 properly handles test2.py and improperly handles test1.py. |

More precisely, the bug is, that 2to3 refactors the "print()" invocation in "test1.py" though it shouldn't because a "print_function" future import is present at the beginning of "test1.py". The cross-check with "test2.py" shows that this is due to the multi-line future import in "test1.py" because the line-break in the import statement is the only difference between both files. |

still having this issue with 2to3 from python-tools-2.7.8-11 as packaged by Fedora 21. Any progress since 2011? |
