how implement a function to iterate over if its passed a Range

I'm creating my own version of .each method in Ruby and I'm having trouble implementing it to work for the input of a Range (1..10).

module Enumerable
  # @return [Enumerable]
  def my_each
    return to_enum :my_each unless block_given?

    index = 0
    while index < size
      if is_a? Array
        yield self[index]
      elsif is_a? Hash
        yield keys[index], self[keys[index]]
      elsif is_a? Range
        yield self[index]
      end
      index += 1
    end
  end
end

I trying to get it to, if passed

r_list = (1..10)
r_list.my_each { |number| puts number }

The output would be

Solution

One technique, that changes very little of this implementation, would be to convert your range to an array.

module Enumerable
  def my_each
    return to_enum :my_each unless block_given?

    index = 0
    while index < size
      if is_a? Array
        yield self[index]
      elsif is_a? Hash
        yield keys[index], self[keys[index]]
      elsif is_a? Range
        yield to_a[index]
      end
      index += 1
    end
  end
end

r_list = (1..10)
puts r_list.my_each { |number| puts number }

Result:
