`Range#last(n)` with a single-element of Integer returns an empty Array. It should return a one-element Array. Interestingly, when the element is a String, `last(n)` returns a one-element Array, expectedly. I have checked the behav...masasakano (Masa Sakano)
The returned values of Range#size between Rational and Float and also with regard to `exclude_end` of true and false are inconsistent. The example below highlights the difference. The first and second should return the same value. The...masasakano (Masa Sakano)
When a (Numeric) argument is given to `Range#last(n)` for a Range with `Float::INFINITY`, it runs into an infinite loop (see a small code snippet below). There is no use case for the feature as far as I can think of, and it is hard to d...masasakano (Masa Sakano)
