I agree with you on this being a better notation. It unclutters the class 
definition. Had Guido suggested the alternative slot syntaxes back at the 
start of November I would have used one of the alternative syntaxes instead 
of creating a new builtin function.  BTW, adding a builtin function is a 
pain. The trick of counting the number of parameters to determine behavior 
caused strange things to happen during the testing of the addmember function.

Is someone working on an implementation of this?
