After Ruby 2.2, Range#include? on non-number-or-time-ish ranges checks all possible values in the range for equality, which is slower but more accurate. Range#cover? uses the previous logic of comparing a value with the range endpoints, which is fast but is only accurate on ::Numeric, ::Time, ::Date, or ::DateTime ranges.
