Hi Ken,

We want to also consider the type of preference, that's the one main 
focus. Read my other email, it sums up the ideas that emerged.

In your example you get rid of Preferences class, and use a class 
variable dictionary in the Preference. Interesting idea, I can't 
evaluate now the drawback, if any, of such a radical option ;-)

Why an informee closure, should not triggering an event at each 
preference value change be enough? Because setter is a block closure 
too? The extensive use of closure makes the code hard to understand, at 
least for me. Let's see what other think about it.

Wish you good recover

Hilaire
