I have my own theory, but I haven't seen the implementation yet. Or
maybe it's something simple, and I am just making things complicated.
Here goes:


-> irb
irb(main):001:0> b,c = 1,2
=> [1, 2]
irb(main):002:0> a = b,c = 1,2
=> [1, 1, 2]
irb(main):003:0> a
=> [1, 1, 2]
irb(main):004:0> a.inspect
=> "[1, 1, 2]"
irb(main):005:0> a.class
=> Array
irb(main):006:0>
