[plt-scheme] "appending" to classes rather than extending

You could achieve this kind of effect (via units) but re-definitions  
in a module (and that's what this boils down to) of the same name are  
frowned upon in Scheme. -- Matthias

P.S. Re-definitions at the top-level have been around for a LONG time  
and there is a reason why Schemers are moving away from that approach.
