-"""Fixer that changes map(F, ...) into list(map(F, ...)) unless there
-exists a 'from future_builtins import map' statement in the top-level
-namespace.
-
-As a special case, map(None, X) is changed into list(X).  (This is
-necessary because the semantics are changed in this case -- the new
-map(None, X) is equivalent to [(x,) for x in X].)
-
-We avoid the transformation (except for the special case mentioned
-above) if the map() 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
-map(F, X, Y, ...) to go on until the longest argument is exhausted,
-substituting None for missing values -- like zip(), it now stops as
-soon as the shortest argument is exhausted.
