Very surprised about this behavior, IMHO it is wrong, at least it is
inconsistent :

irb(main):007:0>  a=[1,[2,[3,4],5],6]
=> [1, [2, [3, 4], 5], 6]
irb(main):008:0>  a.join(",")
=> "1,2,3,4,5,6"
irb(main):009:0>  b=[1,{2=>42},{3=>[4,5]}]
=> [1, {2=>42}, {3=>[4, 5]}]
irb(main):010:0>  b.join(",")
=> "1,242,345"
