kzc	1e51586996	Support marking a call as pure ... A function call or IIFE with an immediately preceding comment containing `@__PURE__` or `#__PURE__` is deemed to be a side-effect-free pure function call and can potentially be dropped. Depends on `side_effects` option. `[#@]__PURE__` hint will be removed from comment when pure call is dropped. fixes #1261 closes #1448	2017-02-21 14:24:18 +08:00
