+Could output a 2nd `with ()` which catches const violations:
+
+```js
+x => with$0 => {
+  with ({get x() { return x; }, set x(v) { const x = 0; x = 0; }}) with (with$0) return () => { x = 2; };
+}
+```
+
+Or for a silent const, a setter which does nothing:
+
+```js
+x => with$0 => {
+  with ({get x() { return x; }, set x(v) {}}) with (with$0) return () => { x = 2; };
+}
+```
+
+If multiple `with` blocks, would need to put the "protector" `with` outside the last `with`.
+
+This same technique could be used to prevent mutating consts in `eval()`.
