Syntax error: No method visitExtend

[Cactusbone]

I'm getting the error Syntax error: No method visitExtend on
@extend $someVariable

$someVariable is defined in another file, imported earlier in the checked file

$someVariable
  line-height normal

I have the same problem with using @extend in any usecase (even if this directive and placeholder selectors are in the same file).

// --- file.styl
$plhSelector
  width: 100px

.mySelector
  @extend $plhSelector

The same problem when i use common selector instead of placeholder selector:

// --- file.styl
.commonSelector
  width: 100px

.mySelector
  @extend .commonSelector

stlint directives @stlint-ignore/@stlint-disable/@stlint-enable don't help to ignore this error.

Is there any way to use @extend and stlint simultaneously?
