maybe for another CL, but ideally we should never end up here.
operator$EQ should simply say:
if (typeof x == "boolean") return x === other;

[John Lenz, 2011/10/14 21:26:40]

yes. I leave that for another CL. After we have golem back up and running.

-  if (typeof other == 'boolean') {
-    return this == other;
-  } else if (other instanceof Boolean) {
-    // Must convert other to a primitive for value equality to work
-    return this == Boolean(other);
-  } else {
-    return false;
-  }
+  return typeof other == 'boolean' && this == other;
 }
 
 function native_BoolImplementation_toString() {

Same is true here. Since we already need to intercept 'toString', to support
null.toString, we should intercept booleans there too.

[John Lenz, 2011/10/14 21:26:40]

true, there is less need for this to be special cased, I think.

-  return (this == true) ? "true" : "false";
+  return this.toString();
 }
+
+function native_BoolImplementation_toBool() {
+  return this == true;
+}
