/* 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.
