A bounded method!
The clamp method is defined in the Comparable module. It is used to bound a value. It is more efficient and explicit than the « classic » [[1, 3].max, 4].min.
The min and max arguments can be nil to indicate no limit.
A Range argument can be used.
⚠️ The Range must be inclusive. The type of object returned depends on arguments.
