Oooh -- don't know. In reality I found that if I really abstract of
attributes of objects (or ADTs in general), the attribute has no 1:1
representation in the implementation. Getting and setting become
fundamentally different then: i'd have to implement them separately
anyway. And often I only want to export the attribute read-only
(indeed that is the often default in base classes anyway), so I don't
want to provide a setter. Some "setter functions" don't even make much
sense when setting a single attribute. 

So overall I found I can well forgo using the pre processor like this.

And custom syntax should anyway be used very sparingly and only if you
do something really different or new AND know what you're doing: Else
the program becomes quickly unreadable locally. And most people with a
pre processor at their finger tipps don't realize that they shouldn't
and -- well -- the results a regrettable.
