humm...I agree with Kent Beck and Stef, because conceptually a String shouldnt know how to answer #seconds.

Maybe its a matter of having better interactions, smarter text morphs , than introducing this in the "model".

maybe where are discussing what we prefer...if nice in words/language or better in OOP.

For example, I may (not sure) agree Number understands #seconds. But I may think also that a better OOP would not Number understand #seconds but stead have Duration seconds: 3

But...'3 seconds' is nicer...it is more similar to our language.
