Just for completeness, the problem with Array.new(6, []) isn't Ruby's
object model - it's that Array.new(num, object) stores a reference to
the object passed in in each of its cells, not a copy of it. There's no
ruby-decreed reason it couldn't have been written to call object.dup
each time it filled a new cell.
