-"""Fixer that changes filter(F, X) into list(filter(F, X)).
-
-We avoid the transformation if the filter() call is directly contained
-in iter(<>), list(<>), tuple(<>), sorted(<>), ...join(<>), or
-for V in <>:.
-
-NOTE: This is still not correct if the original code was depending on
-filter(F, X) to return a string if X is a string and a tuple if X is a
-tuple. That would require type inference, which we don't do. Let
-Python 2.6 figure it out.
