-This rule raises an issue when the argument to or the return type from the functions `list()`, `tuple()`, `set()`, `sorted()`, or `reversed()` are unnecessarily casted.
+This rule raises an issue when the functions `list()`, `tuple()`, `set()`, `sorted()`, or `reversed()` are unnecessarily wrapped around each other's return values or used to convert values that don't require conversion.

 == How to fix it
 
-When the outer function is given a collection but could be given an iterable, the unnecessary cast to the collection should be removed. For example, in `sorted(list(iterable))`, the outer `sorted()` function can accept an iterable directly, so the inner `list()` call is redundant and should be removed.
