-------------------------------------------------------

I'm happy with a (meaningful) exception at runtime. I dislike the idea of it 
falling back to the non-overridden component. As I said, in some cases the only 
fix available is to extend the component you want to override.

> It would be nice to allow global component replacement by a different 
> component class (or derived version from the original) compared to the field 
> type provided. So @InjectComponent would behave more or less like @Inject for 
> services without the need of Interfaces. 
> NOTE: 
> current workaround is decorating ComponentInstantiatorSource 
> As Thiago outlines my workaround is sub-optimal as it bases on internal 
> classes which might subject to change without notice. He suggests to have an 
> Service we can contribute our "overrides" to. Replaceing components would 
> introduce a new level of flexibility to change implementations without 
> touching tml's at all. Naturally ServiceBinder was not my suggested place for 
> this new kind of "binding", seems to be a misunderstanding. From a functional 
> point of view I was just thinking about something like...
>       public static void bind(final ComponentBinder binder)
>       {
>               binder.bind(ComponentA,class, ComponentBderivedFromA.class);
>       }
> ...this, as an example.
