I am learning C++ having experience with Smalltalk. My question refers to the
use of the pseudovariable "this". In Smalltalk, one can use the pseudovariable
self, to refer to the object which received the message. In particular, one
can use it inside of a method of one of the superclasses of the object, to
send messages to it. (something like, [self amessage]). This allows to write
methods at the superclass level which send messages to invoke methods which
are implemented at the subclass level.
Example : can I write :

		int C::foo (...)
		 {
			...
		   this.message
			...
		 }

where "message" is a virtual function declared in class C.
