class RubbyCop::Cop::Performance::RangeInclude
This cop identifies uses of `Range#include?`, which iterates over each item in a `Range` to see if a specified item is there. In contrast, `Range#cover?` simply compares the target item with the beginning and end points of the `Range`. In a great majority of cases, this is what is wanted.
Here is an example of a case where `Range#cover?` may not provide the desired result:
('a'..'z').cover?('yellow') # => true
