Nested inner for comprehensions accumlate when outer does not accumlate

More info please? I would love to take a look at it tomorrow, specially if
you think it should be part of the next release.

_ = for y <- x do
  for z <- y do
    side_effect_fun(b)
  end
end
:return_other

The inner for is accumulated and reversed. Of course this can be avoided by ensuring it is returning a useless value after the inner for:

_ = for y <- x do
  _ =for z <- y do
    side_effect_fun(b)
  end
  :other_return
end
:return_other

However maybe we can handle the first case too.
