• /* FIXME :
   :extend() is not handled specifically : its highlighting is buggy.
   Mixin usage must be inside a ruleset to be highlighted.
   At-rules (e.g. import) containing interpolations are buggy.
   Detached rulesets are highlighted as at-rules.
   A comment before a mixin usage prevents the latter to be properly highlighted.
