Extend binding API to create aliases

we want to have something like

bind(IFoo1.class).to(Foo.class);
bind(IFoo2.class).to(Foo.class);
@Singleton class Foo {} 

But the issue is that doing so would create to 2 Foo instances, kept in internal providers for the keys Foo1 and Foo2.

It would be nice to have something like an alias

bind(IFoo2.class).asAliasOf(IFoo1.class);

so that the keys Foo1 and Foo2 would point to the same internal provider.

In my opinion the expected behavior for this code is to create a single instance of Foo without any aliases. Otherwise what does @Singleton mean here?

Yes, seems like a viable option!
