The ability to do the cast requires an IS-A relationship. I would prefer
something like:
T t = (T) context.get(T.class);
and I believe that this better satisfies your examples, as well. There is
nothing here that talks about implementation. It simply says that a context
can have multiple interfaces, and that there is a method on the context by
which to acquire a specific one.
This is just a strawman. I've left out exception/error handling, and well
as a .has(Class) method, and I'm not married to the idea that this is a
Context method, although I believe that to be the right place.
Workable? :-)
