Is it possible to prohibit an injection?

I'm using a couple of different injectors and I want to ensure I don't accidentally access a class that's bound automatically from an injector, especially since its scope is important.

Is there a way I can force an automatic binding to fail, or at least report a run-time error?

For instance if I have a method Foo that is "illegally" requesting a Bar:

class Bar { @Inject Bar() {} } // Shouldn't be accessible in Foo's injector
class Foo { @Inject Foo(Bar bar) {} } // Binding should fail here

Thanks Sam, but doesn't that force explicit bindings for all classes?  I take it there's no way to prohibit bindings to just a handful of classes?  I suppose I could make a provider method that throws a runtime exception?
