Inaccurate errors returned by compiler #448

I'm currently building an Angular app using template from your yeoman generator. There is one thing that annoys me and I think it should be fixed.

This is how "Internal Server Errors" are being shown in my project:

Information I've received is highly inaccurate. Message tells me that there is some unexpected token somewhere in my code and in files like http.umd.js, main-server.js or \rxjs\Subscriber.js which is not true, because problem happens in my code, not in components I import.

Is there any way I could improve quality of error messages I receive? I mean: is it possible to include in such error message exact position of faulty code? Or at least name of file where it happens?

Additional info:
Type of generated project: Angular2
