+* Tests
+* Deal with duplicate bindings:
+  * Hoisted sloppy functions - actually no need, because `isFunction` means both are frozen anyway
+  * `for (let x of (() => x, [])) eval('x');` - done, but write test
+  * `function (x, _ = eval('x')) { var x; return x; }` - done (apart from `arguments`), but write test
+* Tests for binding in higher scope which is shadowed still not being renamed
+  e.g. `() => { let x = 1; { let x; eval('typeof a !== "undefined" && a = 2'); } return x; }` - make sure param `x` not renamed to `a`
+  * Make sure this includes vars which are illegal to access inside `eval()` if `eval()` is strict mode.
+* Test for const violations with frozen vars when internal to function:
+
+```js
+module.exports = function(module, exports) {
+	const x = 1;
+	eval('x');
+	return () => { x = 2; };
+};
+```
+
+Also where another binding which isn't frozen:
+
+```js
+module.exports = function(module, exports) {
+	const x = 1;
+	eval('x');
+	{ const x = 2; }
+	return () => { x = 2; };
+};
+```
