For one, it would be mighty polite of the compiler to demangle the "_** D8infinity8standard7runtime4IA**pp4IApp11__InterfaceZ", which happens to be "infinity.standard.runtime.App.App.__Interface". The ModuleInfo is a half-working runtime reflection structure, which the compiler successfully fails to build when you omit the optional module declaration. -- Bye, Gor Gyolchanyan.
