Hehe - yeah :)

The example given is fine for my own personal use, but I shouldn't 
expose that sort of thing as part of an API :)

The easy and clean remedy is to use an interface instead, but in this 
case I was hoping to expose something "lightweight" instead. Any ideas 
for a practical resolution?
