già che ci siamo, io farei

class Foo  
def initialize(args)  
…  
end  
def close  
…  
end  
def process(&block)  
block.call(self)  
ensure # def… end funziona come begin…end  
self.close()  
end

def self.process(args, &block) # classmethod  
new(args).process(&block)  
end

così da mimare l’interfaccia di File.open e simili:

Foo.process(something) do |foo|  
foo.stuff  
end
