On second thought, maybe I shoudln't make a new error type.

-  {
-  public:
-    JsValueError(v8::Isolate* isolate, const char* filename, int line);
-    static std::string ErrorToString(const char* filename, int line);
+    static std::string ErrorToString(const char* message,
+      const char* filename, int line);
   };
 }
