It's not important here, but I saw it in some other codereviews. To avoid
undesired indentation of function bodies one can use
void FilterNotifier::FilterChange(...
in cpp file and the function will be correctly found by linker.

Done.

+                                      exports.Filter.fromPointer($1));
+    }, topic, filter);
+  }
