Subject: Adjusting the Scope of Blocks

Hi,

Is there a way to give a block associated with a method call the same scope 
as if it were executing inside the method.

ie.

class Foo
   ACONST = 1

   def input_flags
        @FLAG_SEL = INPUT
        yield
   end

   def output_flags
        @FLAG_SEL = OUTPUT
        yield
   end

   def set(flgs)
        set_flags(@FLAG_SEL, flgs)
   end
end

f = Foo.new

f.input_flags {
  set ACONST
}

f.output_flags {
  set ACONST
}

Thanks in advance.
