32 * namely prioritize {@code getMethod} over {@code getElem} or {@code getProp}. An access or ident node with isFunction
33 * set to true will be emitted as {@code dyn:getMethod|getProp|getElem} while one with it set to false will be emitted
34 * as {@code dyn:getProp|getElem|getMethod}. Similarly, an index node with isFunction set to true will be emitted as
35 * {@code dyn:getMethod|getElem|getProp} while the one set to false will be emitted as {@code dyn:getElem|getProp|getMethod}.
