Had to change this - jshydra doesn't handle function expressions anymore as of
https://issues.adblockplus.org/ticket/427.

[Wladimir Palant, 2015/04/29 17:42:57]

Why not change it into |() => values[key]|? Note that ideally this would also
use Object.defineProperty() (see https://issues.adblockplus.org/ticket/653).

[Felix Dahlke, 2015/04/30 05:06:11]

Done.

-  Prefs.__defineSetter__(key, function(value)
+  Object.defineProperty(Prefs, key,
   {
-    if (typeof value != typeof defaults[key])
-      throw new Error("Attempt to change preference type");
+    get: () => values[key],
+    set: function(value)
+    {
+      if (typeof value != typeof defaults[key])
+        throw new Error("Attempt to change preference type");
 
-    if (value == defaults[key])
-      delete values[key];
-    else
-      values[key] = value;
-    save();
+      if (value == defaults[key])
+        delete values[key];
+      else
+        values[key] = value;
+      save();
 
-    for (let listener of listeners)
-      listener(key);
+      for (let listener of listeners)
+        listener(key);
+    },
+    enumerable: true
   });
