This is even a bit restricting since it may not tell you all you
need to know to be compatible. For instance, it may be that the
object subclasses NSObject but still implements the protocol you
need - so you can call conformsToProtocol: to see if this is true.
If there is a formal protocol defined, this is probably the best
way to check if the object is what you expect.
If you're using a formal protocol, you can also check at compile-
time, by declaring it as part of the type:
-(void)foo: (id<ProtocolName>)bar;
