Hmm unless I am missing something here there is no need to raise
NoMethodError with super just to
rescue it immediately
What about

def method_missing sym
    fetch( sym ) do
      fetch( sym.to_s) do
        raise NoMethodError,"undefined method #{sym} for
        #{self.inspect}:#{self.class} overridden by Mac's redefinition of
        Hash::method_missing in #{__FILE__}"
      end
   end
end

Si tu veux construire un bateau ...
Ne rassemble pas des hommes pour aller chercher du bois, préparer des
outils, répartir les tâches, alléger le travail… mais enseigne aux
gens la nostalgie de l’infini de la mer.

If you want to build a ship, don’t herd people together to collect
wood and don’t assign them tasks and work, but rather teach them to
long for the endless immensity of the sea.
