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 :p)

If you don't need setters, but only accessors 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.
