BUILD if I recall is called on every class in the inheritance chain so you
would only need it set once to get this behavior.

Thank you Yuval,
However I want to avoid putting the call into each BUILD that is the
last in the hierarchy. If I decide to subclass from Two, I have to move
the call manually. The idea behind my question is to be able to check if
all constructors worked "correctly", for example consumed all named
parameters.
