This version of PyFlakes has been improved to use Python's newer ast module, instead of compiler. So code checking happens faster, and will stay up to date with new language changes.

Importing several modules from the same package results in unnecessary warnings:

import a.b
import a.c # Redefinition of unused "a" from line 1

The following construct for defining a function differently depending on some condition results in a redefinition warning:

if some_condition:
    def foo(): do_foo()
else:
    def foo(): do_bar() # redefinition of function 'foo' from line 2
