bug with & (parent-selector) and @each directive in 3.3.2

[lunelson]

-- edit --
The following regression has been identified by @xzyfer as having to do with the @each directive. Current workaround is to use a @for loop instead.

@function last-sels() {
  $out: ();
  @each $list in & {
    $last: nth($list, length($list));
    @if not index($out, $last) {
      $out: append($out, $last, 'comma');
    }
  }
  @return $out;
}

.test .nest {
  content: inspect(last-sels());
}

.test, .other {
  content: inspect(last-sels());
}

resulted in this in 3.2.5

.test .nest {
  content: (.nest,);
}

.test, .other {
  content: .test, .other;
}

but in 3.3.2 does this

.test .nest {
  content: .test .nest;
}

.test, .other {
  content: .other;
}

This appears to be a bug with @each and &. The following changes fixes your issue.

-  @each $list in & {
+  @for $i from 1 through length(&) {
+    $list: nth(&, $i);

ah good catch! I can work with that, shall I update the title of this issue?

[xzyfer]

Yea please.

Spec added sass/sass-spec#637

Added to the 3.4 milestone since there is a viable workaround.
