Comment 2 for bug 1153355

fwiw, as of v1.2.0, the error message is less confusing as the name in the error message now matches what appears on the line of the source code:

./aaa.py:2: 'os.path' imported but unused

This was done with

https://github.com/pyflakes/pyflakes/commit/aec68a7847d8dbd1371242f42f9302103a68178f

It had a few bugs (lp:1560134 and lp:1578051), which have fixes yet to be released.

It still does not detect that both are unused, which turns out to be a spectacularly difficult problem to solve in pyflakes, but we're getting closer.
