  class Foo
    attr_accessor :bar
  end
  a = Foo.new
  a.bar = 1
  p a                              #>> #<Foo:0x81c6600 @bar=1>
  p a.instance_variables           #>> ["@bar"]
  a.instance_eval {@bar}           #>> 1
  a.instance_variable_get("@bar")  #>> 1
  a.instance_variable_set("@baz",2)
  p a                              #>> <Foo:0x81c6600 @baz=2, @bar=1>

The last two examples show reading/writing instance variables by name, is
that what you were trying to do?
