Subject: Idiom -- is there a better way?


Hi ..

I am doing indirect dispatch, something like:

  class Foo
    def bar(fn)
      eval "self.#{fn}"
    end
  end

  class Bar < Foo
    def blah
      puts "blah here"
    end
  end

  f = Bar.new
  f.bar("blah")

It works however I am sure there must be a nicer way of doing the bar(fn) 
stuff.  Any ideas?

TIA,
-mark.
