I don't have much experience with Erlang, but that also seems wrong:

  1> Xss = [[1]].
  [[1]]
  2> [ X || X <- Xs, Xs <- Xss].  
  * 1:13: variable 'Xs' is unbound
  3> [ X || Xs <- Xss, X <- Xs].
  [1]

Damnit. I haven't used Erlang in a long time, but I should've known that.

So, no language does it "right".
