Because numbers (Fixnums) do not implement the each method as numbers are
not collections - ranges do, though. To call the method on the range instead
of the last Fixnum that forms the range, enclose it in parantheses:

$ irb
irb(main):001:0> 1..10.each {|x| puts x}
NoMethodError: undefined method `each' for 10:Fixnum
        from (irb):1
irb(main):002:0> (1..10).each {|x| puts x}
1

9
10
=> 1..10
