Its current behaviour is to assign to $bar[0] the length of @foo repeated
twice.

  DB<1> @foo = (1,2,3)

  DB<2> @bar = @foo x 2

  DB<3> p "@bar"
33
  DB<4> p $bar[0]
33

This is what I call less than useless, perhaps you are thinking of,
the current behavior of @bar = (@foo) x 2

  DB<5> @bar = (@foo) x 2

  DB<6> p "@bar"
1 2 3 1 2 3

Which has real application.
