I'd settle for a warning when run with -w. This code emits a warning 
when run with -w:

# redef.rb
class Foo
    def bar
       puts "hello"
    end

    def bar
       puts "world"
    end
end

redef.rb:6: warning: method redefined; discarding old bar

But this does not:

# redef2.rb
class Foo
    def bar
       puts "hello"
    end
end

class Baz < Foo
    def bar
       puts "world"
    end
end

Is there any way to make the 2nd case emit a warning without major 
changes to core Ruby?
