Hm, the following 
   
    def x.foo; end

where  x == nil,false or true always worked - the interpreter
only starts complaining if I do something like

   class << nil; end,

but this is a pretty mood point since the NilClass and Boolean class are 
build in OO-Singleton classes anyway - and I can always write

    class NilClass
        Pointless = "Const" 
        def each(*args);   nil end
        class << self;
            def each_nil; yield nil end
        end  
     end
