RUBY_RESERVED_KEYWORDS =

Ruby reserved words. A call like ‘self.class` — when stripped of its `self.` receiver — becomes the bare token `class`, which the parser reads as the class-definition keyword rather than a method call. Producing this mutation guarantees an unparseable result. Skip when the call’s method name collides with any reserved keyword.
