The idea was OK but the details were broken.  What I wrote before 
does not, of course, work when the subclass overrides foo, which we 
must assume that it does,that being the reason that we want to call 
"super foo"!

What you actually have to do is go to the superclass and copy the 
body of foo into basicFoo.  Then redefine foo as "self basicFoo". 
Then the trick works.  Of course, you have to generate a new version 
of the name "basicFoo" each time that you do this in an inheritance 
chain.  This is exactly what is going on whith basicNew and new.
