/* 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.
