The compiler doesn't perform static type checking on expressions of
type id.  So as long as someone, somewhere has declared a
-doFoo:withBar:baz: method, I can send that message to an id.

Once you specify NSObject, though, the compiler assumes that your
object only responds to messages in that interface/protocol.  Makes
"NSObject *foo" kind of useless unless you only need to send NSObject
messages to it.
