Use the exact same code as I gave for the Hash object, but use the 
class of your choice there. (To make things really ugly, do this on 
Object, and EVERYTHING in Ruby will behave this way...at least, 
everything that supports the [] and []= methods :p)

If you don't need setters, but only getters via dot notation, it can be 
simplified to:


class SomeClass
    def method_missing(meth,*args)
       /=$/=~meth.id2name ? nil : self[meth]
    end
end


All this said, you should think hard before you do this, since it will 
make your code somewhat un-ruby-like; further, you run a strong risk of 
running into confusing problems, where you think you're accessing a 
property by name but are in fact invoking a method.
